PM155J high-performance JFET-input operational amplifier )(NOS)

This high-performance JFET-input operational amplifier has a very low input bias current of typically under 50 pA, resulting in improved accuracy and stability. Its 5 V/µs slew rate and 2.5 MHz gain bandwidth product make it ideal for precise and high-speed applications. With an input offset voltage of typically 1.0 mV and an operating temperature range of -55^\circC to +125^\circC, this military/aerospace-grade package is built to withstand harsh environments.

Specifications

 * Function: High-performance JFET-input operational amplifier.

 * Package: The component in your image is in a hermetically sealed metal can, likely a TO-99 (similar to a TO-5) or a similar military/aerospace-grade package.

 * Input Bias Current: Very low, typically under 50 pA. This is a key feature of JFET-input op-amps.

 * Slew Rate: 5 V/µs (volts per microsecond).

 * Gain Bandwidth Product: 2.5 MHz.

 * Input Offset Voltage: Typically 1.0 mV.

 * Operating Temperature Range: The "J" in the part number often indicates a military-grade temperature range of -55^\circC to +125^\circC.

Note: The "8602" on the part in your image is a date code, indicating it was manufactured in the 2nd week of 1986.
