Low Noise , Precision , High Speed. Low -cost, high-volume production of the OP37 is achieved by. OP37 A. OP37 E Z. Current limiting resistors. ESD electrostatic discharge sensitive device. Electrostatic charges as high as V readily. Therefore, proper ESD precautions. Time over extended periods after the first 30 days of operation.

Excluding the initial. Electrical tests are performed at wafer probe to the limits shown. Due to variations in assembly methods and normal yield loss, yield after packaging is not guaranteed.

Consult factory to negotiate specifications based on dice lot qualification through sample lot assembly and testing. OP37 offset voltage may be nulled to. Otala, M. Stout, D.

Edits to Caption for TPC Added Caption to Figure 2. Added Caption to Figures 4a and 4b. Added Caption to Figures 8— Offsets down to 25 mV and a maximum drift of 0. The low input bias current of 10 nA and offset current of 7 nA are achieved by using a bias-current cancellation circuit.

These characteristics, coupled with long-term drift of 0. This reliable and stable offset trimming scheme has proved its effectiveness over many years of production history. B Information furnished by Analog Devices is believed to be accurate and reliable. However, no responsibility is assumed by Analog Devices for its use, nor for any infringements of patents or other rights of third parties that may result from its use.

No license is granted by implication or otherwise under any patent or patent rights of Analog Devices. V— One Technology Way, P. Box , Norwood, MA , U. The OP37 provides the low offset and drift of the OP07 plus higher speed and lower noise. A guaranteed swing of 10 V into W and low output distortion make the OP37 an excellent choice for professional audio applications.

Low -cost, high-volume production of the OP37 is achieved by using on-chip zener-zap trimming. The OP37 brings low-noise instrumentation-type performance to such diverse applications as microphone, tapehead, and RIAA phono preamplifiers, high-speed signal conditioning for data acquisition systems, and wide-bandwidth instrumentation. Indefinite Differential Input Voltage Note2.

Current limiting resistors are not used in order to achieve low noise. If differential input voltage exceeds 0.

Electrostatic charges as high as V readily accumulate on the human body and test equipment and can discharge without detection. Although the OP37 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

Excluding the initial hour of operation, changes in V OS during the first 30 days are typically 2. NULL 2. Due to variations in assembly methods and normal yield loss, yield after packaging is not guaranteed for standard product dice. Input Bias Current vs. Temperature TPC Input Offset Current vs.

Additionally, the OP37 may be fitted to unnulled type sockets; however, if conventional nulling circuitry is in use, it should be modified or removed to ensure correct OP37 operation. OP37 offset voltage may be nulled to zero or other desired setting using a potentiometer see figure 1.

Closed loop gain must be at least five. For closed loop gain between five to ten, the designer should consider both the OP27 and the OP For gains above ten, the OP37 has a clear advantage over the unity stable OP Thermoelectric voltages generated by dissimilar metals at the input terminal contacts can degrade the drift performance.

Best operation will be obtained when both input contacts are maintained at the same temperature. However, if further adjustment of V OS is necessary, a 10 kW trim potentiometer may be used. TCV OS is not degraded see offset nulling circuit. Other potentiometer values from 1 kW to 1 MW can be used with a slight degradation 0. If smaller adjustment range is required, the nulling sensitivity can be reduced by using a smaller pot in conjunction with fixed resistors.

As shown in the warm-up drift curve, the offset voltage typically changes 4 mV due to increasing chip temperature after power up. In the ten second measurement interval, these temperatureinduced effects can exceed tens of nanovolts. Shielding minimizes thermocouple effects.

As shown in the noise-tester frequency response curve, the 0. The test time of ten seconds acts as an additional zero to eliminate noise contributions from the frequency band below 0. A 10 Hz noise-voltage-density measurement will correlate well with a 0. Optimizing Linearity Best linearity will be obtained by designing for the minimum output current required for the application. Instrumentation Amplifier A three-op-amp instrumentation amplifier, shown in figure 4, provides high gain and wide bandwidth.

The input noise of the circuit below is 4. The gain of the input stage is set at 25 and the gain of the second stage is 40; overall gain is The amplifier bandwidth of kHz is extraordinarily good for a precision instrumentation amplifier.

Set to a gain of , this yields a gain bandwidth product of MHz. The full-power bandwidth for a 20 V p-p output is kHz. Instrumentation Amplifier REV. The outstanding input voltage noise characteristics of the OP37 are achieved mainly by operating the input stage at a high quiescent current.

The input bias and offset currents, which would normally increase, are held to reasonable values by the input bias current cancellation circuit. This is particularly important when the input has a high source resistance.

In addition, many audio amplifier designers prefer to use direct coupling. The high I B. TCV OS of previous designs have made direct coupling difficult, if not impossible, to use. Noise vs. Resistance Including Resistor Noise Hz Voltage noise is inversely proportional to the square-root of bias current, but current noise is proportional to the square-root of bias current. Figures 5, 6, and 7 compare OP observed total noise with the noise performance of other devices in different circuit applications.

The same plot applies to wideband noise. To use this plot, just multiply the vertical scale by the square-root of the bandwidth.

This article will describe the faults of common power systems with a focus on how they affect op-amp audio applications. First, some terminology. The primary parameter to be concerned about is the impedance of the cells you will be using. A practical storage cell cannot put out infinite current, so its effective impedance must be greater than zero.

This device offers a wide range of connection protocols which are rounded up with other useful features. As a result, in a thin client, performance is limited and more sophisticated functionality, such as real-time automatic segmentation and fly-through, are usually not possible.

Frequency response of operational amplifiers. Relation between bandwidth and gain. Slew rate. Design of first order active filters with operational amplifiers. Before building filters with o perational amplifiers so called active filters we have to investigate the frequency response of a simple op-amp circuit. The circuit behaves, in fact, like a low pass filter and thus can be used as an amplifier only in a limited frequency range.

How good is it? User Name Stay logged in? But in the test, OP27 got higher praises. I am wondering if anyone knows how good OP27s sound. The OP27, if memory serves, it is related to the OP37, with one being decompensated and the other not. Dejan Veselinovic mentions that the OP27 is used in the highly regarded Burmester gear.
