NJM4556AD

JRC · Operational Amplifier · DIP-8

NJM4556AD from JRC, in a DIP-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 A OUTPUT output Output of op-amp A, which can drive ±70mA into 150Ω loads with ±10.5V minimum output swing.
2 A -INPUT input Inverting input of op-amp A; the input voltage must stay within ±15V absolute maximum (limited to the supply voltage when the supply is below ±15V).
3 A +INPUT input Non-inverting input of op-amp A; the input voltage must stay within ±15V absolute maximum (limited to the supply voltage when the supply is below ±15V).
4 V- power_in Negative supply pin; the device operates from ±2V to ±18V supplies with an absolute maximum of ±18V.
5 B +INPUT input Non-inverting input of op-amp B; the input voltage must stay within ±15V absolute maximum (limited to the supply voltage when the supply is below ±15V).
6 B -INPUT input Inverting input of op-amp B; the input voltage must stay within ±15V absolute maximum (limited to the supply voltage when the supply is below ±15V).
7 B OUTPUT output Output of op-amp B, which can drive ±70mA into 150Ω loads with ±10.5V minimum output swing.
8 V+ power_in Positive supply pin; the device operates from ±2V to ±18V supplies with an absolute maximum of ±18V.
