OP37AJ

Datasheet OP37 Low Noise, Precision, High Speed Operational Amplifier The OP37 provides the same high performance as the OP27, but the design is optimized for circuits with gains greater than five. This design change increases slew rate to 17 V/µs and gain-bandwidth product to 63 MHz. The OP37 provides the low offset and drift of the OP07 plus higher speed and lower noise. Offsets down to 25 µV and a maximum drift of 0.6 µV/°C make the OP37 ideal for precision instrumentation applications. Exceptionally low noise (en= 3.5 nV/ @ 10 Hz), a low 1/f noise corner frequency of 2.7 Hz, and the high gain of 1.8 million, allow accurate high-gain amplification of low-level signals.

A guaranteed swing of 10 V into 600 W and low output distortion make the OP37 an excellent choice for professional audio applications.

These characteristics, coupled with long-term drift of 0.2 mV/month, allow the circuit designer to achieve performance levels previously attained only by discrete designs. Low-cost, high-volume production of the OP37 is achieved by using on-chip zener-zap trimming. This reliable and stable offset trimming scheme has proved its effectiveness over many years of production history. GENERAL DESCRIPTION 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. The OP37 provides the same high performance as the OP27, but the design is optimized for circuits with gains greater than five. This design change increases slew rate to 17 V/ms and gain-bandwidth product to 63 MHz. PIN CONNECTIONS The OP37 provides the low offset and drift of the OP07 plus higher speed and lower noise. Offsets down to 25 mV and a maximum drift of 0.6 mV/∞C make the OP37 ideal for precision instrumentation applications. Exceptionally low noise (en= 3.5 nV/ @ 10 Hz), a low 1/f noise corner frequency of 2.7 Hz, and the high gain of 1.8 million, allow accurate high-gain amplification of low-level signals. 8-Lead Hermetic DIP (Z Suffix) Epoxy Mini-DIP (P Suffix) 8-Lead SO (S Suffix) The low input bias current of 10 nA and offset current of 7 nA are achieved by using a bias-current cancellation circuit. Over the military temperature range this typically holds IB and IOS to 20 nA and 15 nA respectively.

NOTES 1 For supply voltages less than 22 V, the absolute maximum input voltage is equal to the supply voltage. 2 The OP37’s inputs are protected by back-to-back diodes. Current limiting resistors are not used in order to achieve low noise. If differential input voltage exceeds 0.7 V, the input Current should be limited to 25 mA. 3 ␪JA is specified for worst case mounting conditions, i.e., ␪JA is specified for device in socket for TO, CerDIP, P-DIP, and LCC packages; ␪JA is specified for device soldered to printed circuit board for SO package. 4 Absolute maximum ratings apply to both DICE and packaged parts, unless otherwise noted. CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 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. –2– WARNING! ESD SENSITIVE DEVICE REV.
