JFET op-amp in a hermetically sealed TO-99-8 can
The PM156J/883C is a single-circuit JFET-input operational amplifier from Analog Devices, part of the Military MIL-STD-883 series. It delivers a 5 MHz gain-bandwidth product and a 12 V/µs slew rate, making it suitable for precision analog signal conditioning in high-reliability systems where speed and accuracy are required. The device operates over the full military temperature range of -55°C to 125°C and supports a supply voltage span up to 44 V, giving designers ample headroom for single- or split-rail topologies in avionics, defense, and industrial control.
Parametric profile and what it means for your BOM
Input bias current is 30 nA typical, and input offset voltage is 1 mV typical — figures that keep DC errors low in high-impedance sensor interfaces, like photodiode preamplifiers or charge amplifiers. Output drive capability is 50 mA per channel, enough to directly drive a small relay, LED indicator, or analog-to-digital converter input without an external buffer. Supply current is 2 mA typical, a moderate draw that balances performance with power budget in multi-channel systems.
Package, mounting, and compliance
Housed in a TO-99-8 metal can, the PM156J/883C is a through-hole component with a hermetic seal — ideal for environments where moisture, vibration, or thermal cycling could compromise plastic-packaged devices. The part is RoHS non-compliant, meaning it uses tin-lead solder finish. This is standard for MIL-STD-883 devices and is acceptable in defense, aerospace, and other applications with a RoHS exemption.
