ZJA3628ASAER

ZJW · Instrumentation OpAmps · SOIC-8

ZJA3628ASAER from ZJW, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 RG passive Gain setting pin; place the gain resistor between pin 1 and pin 8 (ZJA3628: G = 1 + 50 kΩ/RG, gain range 1 to 10,000).
2 -IN input Inverting analog input.
3 +IN input Non-inverting analog input.
4 -VS power_in Negative power supply; supply operating range is ±2.4 V to ±18 V.
5 REF input Reference input that sets zero-output voltage; must be driven by a low impedance source and should not exceed either supply by more than 1.2 V.
6 OUT output Analog output, developed with respect to the REF pin potential.
7 +VS power_in Positive power supply; supply operating range is ±2.4 V to ±18 V.
8 RG passive Gain setting pin; place the gain resistor between pin 1 and pin 8 (ZJA3628: G = 1 + 50 kΩ/RG, gain range 1 to 10,000).
