This design change increases slew rate to 17V/ys and gain-bandwidth product to 683MHz. The OP-37 operational amplifier combines outstanding low noise performance with precision D.C. characteristics and high speed operation. Wideband noise is 3nV/V/Hz at 10Hz., with a low 1/f noise corner frequncy of 2.7Hz. The OP-37's exceptionally low, noise process allows for accurate high-gain amplification of low level signals. A gain-bandwidth product of 68MHz and a 17V/usec slew rate provides excellent choice for reliable, OP-37 precision amplifier applications. The low input bias current of 10nA and offset current of 7nA are achieved by using a bias- current-cancellation circuit. Over the military temperature range this typically holds I-bias and I-os to 20nA and 15nA respectively. PSRR and CMRR exceed 120dB. These characteristics coupled with long-term drift of 0.2nV/month, allow the circuit designer to achieve performance levels previously attained by discrete designs. PRODUCT HIGHLIGHTS: 1. Precision amplification of very low level, low frequency voltage inputs is enhanced by ultra-low input voltage noise. 2. The OP-37 maintains high DC accuracy due to ultra-low offet voltage, offset voltage drift and input bias current. 3. Internal frequency compensation, factory adjusted offset voltage (zener-zapped) and full device protection eliminate the need for additional components. 4. Long-term stability and accuracy is assured with low offset voltage drift over time. 5, Input errors are greatly reduced by superior common mode and power supply rejection. 6. Radiation hardenable to beyond 5 M Rads. l SIMPLIFIED SCHEMATIC _ PIN CONNECTIONS (Top View) * R12 ARE PERMANENTLY ADJUSTED AT WAFER TEST FOR MINIMUM OFFSET VOLTAGE, NON INVERTING INPUT () j Ne AS 6 Att t+ \W$4 Hy ERTING os ca INPUT (-) : oO 026 , ait) ar t i aay (ove a Ns nq 8 Vgg TRIM OVs O a te nv -IN [2] Ve se -IN2 6 OUT sn => Hs} our re +INID N.C v-[4] 5] N.C. q $s 4 V-(CASE) T0-99 (J-Suttix) arin Sutin). oIP -o : : ouTPUT EPOXY MINI-DIP : (P-Suffix) 4s N Ove 8-PIN PLASTIC SOIC - OP-37BRC (S-Suttix) LCC Package (RC-Suffix)- DICE Junction Temperature.............

The OP-37'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 +40.7V, the input current should be limited to 25mA. 3. For supply voltages less than + 22V, the absolute maximum input voltage is equal to the supply voltage. 4. Absolute maximum ratings apply to both DICE and packaged parts, unless otherwise noted.
