Quad JFET op-amp for precision signal chains
The AD713JNZ packs four JFET-input amplifiers into a single 14-pin DIP, each delivering a 20 V/µs slew rate and 4 MHz -3 dB bandwidth — enough margin for fast-settling multiplexed data-acquisition front-ends or audio processing in the 0–70 °C commercial range. Input bias current sits at 10 pA typical, so the AD713JNZ works directly with high-impedance sensors (photodiodes, pH probes) without a separate buffer stage — the JFET front end keeps the offset drift predictable across the temperature band.
Package and supply rail fit
Housed in a 14-lead PDIP (0.300-inch body), the AD713JNZ is a through-hole part — it breadboards easily and survives rework cycles without moisture sensitivity concerns. The 9–36 V supply span means it runs from ±5 V to ±18 V rails, covering standard industrial split supplies. Each amplifier can source or sink 25 mA, enough to drive a 600 Ω load to ±10 V swing. Supply draw is 10 mA per amplifier quiescent, so the quad package pulls about 40 mA total — well within the thermal budget of the DIP package at 70 °C ambient.
Active production — no end-of-life watch needed
Analog Devices lists the AD713JNZ as Active with RoHS3 compliance.
