... O NOTES For 25°C characterlstics of OP37NT and OP37GT devices, see OP37N and OP37G characteristics, respectively. 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 for standard product dice. Consult factory to negotiate specifications based on dice lot qualification through sample lot assembly and testing. ...

S With R S resistor noise rather than current or voltage noise only beyond Rs of 20kil that current noise starts to dominate. The argument can be made that current noise is not important for applications with low to-moderate source resistances ...

... R3 While the tape-equalization requirement has a flat high frequency gain above 3 kHz (t for unity gain. The decompensated OP37 provides a greater bandwidth and slew rate. For many applications, the idealized time constants shown may require trimming of R optimize frequency response for non ideal tape head perfor- mance and other factors ...
