OP279GSZ-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 rail-to-rail output sources and sinks ±60 mA typical and is short-circuit protected. |
| 2 | IN A | input | Inverting input of amplifier A; input common-mode range spans 0 V to 5 V at a 5 V supply. |
| 3 | +IN A | input | Non-inverting input of amplifier A; rail-to-rail input with common-mode range 0 V to 5 V at a 5 V supply. |
| 4 | V- | power_in | Negative supply rail; the part operates from a 4.5 V to 12 V supply (single-supply operation). |
| 5 | +IN B | input | Non-inverting input of amplifier B; rail-to-rail input with common-mode range 0 V to 5 V at a 5 V supply. |
| 6 | IN B | input | Inverting input of amplifier B; input common-mode range spans 0 V to 5 V at a 5 V supply. |
| 7 | OUT B | output | Output of amplifier B; the rail-to-rail output sources and sinks ±60 mA typical and is short-circuit protected. |
| 8 | V+ | power_in | Positive supply rail; absolute maximum supply is 16 V and the operating supply range is 4.5 V to 12 V. |
