JM38510/11402 Series

The PM156 provides low input current, high slew rate, and direct interchangeability with LF156 type. This operational amplifier uses a new process which allows fabrication of matched JFET transistors and standard bipolar transistors on the same chip. High accuracy make the PM156 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 PM156 include a typical slew rate of 12V/µs, a 2.5MHz gain bandwidth product, and settling time to within ±0.01% of final value in 4.0µs.
