OP Amp Single GP ±20V 8-Pin DIP

The PM JFET-input series provides low input current, high slew rate, and direct interchangeability with LF155, 156, and 157 types. These operational amplifiers use a new process which allows fabrication of matched JFET transistors and standard bipolar transistors on the same chip. High accuracy and low cost make the PM JFET-input series useful in new designs and as replacements for modular and hybrid types. Unlike many designs, nulling the input offset voltage does not degrade common-mode rejection ratio or input offset voltage drift. Low input voltage noise and current noise plus a low 1/f noise corner frequency allow these amplifiers to be used in a variety of low noise, wide-bandwidth applications.Dynamic specifications for the PM-155 include a slew rate of 5V/µs, a 2.5MHz gain bandwidth product, and settling time to wit ±0.01% of final value in 5.0µs. The PM-156 has a slew rate of 12V/µs and a settling time of 4.0µs to ±0.01% of final valve.
