OP275GSZ-REEL7

Analog Devices · Audio Amplifiers · SOIC-8

OP275GSZ-REEL7 from Analog Devices, 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 OUT A output Output of amplifier A; the internal 30 Ω series resistor limits short-circuit current to typically +40 mA / −90 mA at ±15 V, but shorts to either supply may destroy the device.
2 -IN A input Inverting input of amplifier A; input voltage range is ±10.5 V and differential input voltage is clamped to ±7.5 V by internal Zener diodes.
3 +IN A input Non-inverting input of amplifier A; input voltage range is ±10.5 V and absolute maximum input voltage is ±22 V.
4 V- power_in Negative supply rail; specified supply range is ±4.5 V to ±22 V.
5 +IN B input Non-inverting input of amplifier B; input voltage range is ±10.5 V and absolute maximum input voltage is ±22 V.
6 -IN B input Inverting input of amplifier B; input voltage range is ±10.5 V and differential input voltage is clamped to ±7.5 V by internal Zener diodes.
7 OUT B output Output of amplifier B; the internal 30 Ω series resistor limits short-circuit current to typically +40 mA / −90 mA at ±15 V, but shorts to either supply may destroy the device.
8 V+ power_in Positive supply rail; specified supply range is ±4.5 V to ±22 V.
