ADI OP37GSZ

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. The output stage has good load driving capability. A guaranteed swing of 10 V into 600 Ω and low output distortion make the OP37 an excellent choice for professional audio applications. PSRR and CMRR exceed 120 dB. These characteristics, coupled with long - term drift of 0.2 μV / 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. 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.
