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. |
