OPA2356AIDGKR from Texas Instruments, in a VSSOP-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, which swings within 100mV of the rails with a 2.5V to 5.5V supply. |
| 2 | -In A | input | Inverting input of amplifier A; the common-mode input range extends from (V-) - 0.1V to (V+) - 1.5V. |
| 3 | +IN A | input | Non-inverting input of amplifier A; the common-mode input range extends from (V-) - 0.1V to (V+) - 1.5V. |
| 4 | V- | power_in | Negative supply rail, which is ground in single-supply operation; the supply range is 2.5V to 5.5V and voltages above 7.5V absolute maximum can permanently damage the amplifier. |
| 5 | +IN B | input | Non-inverting input of amplifier B; the common-mode input range extends from (V-) - 0.1V to (V+) - 1.5V. |
| 6 | -In B | input | Inverting input of amplifier B; the common-mode input range extends from (V-) - 0.1V to (V+) - 1.5V. |
| 7 | OUT B | output | Output of amplifier B, which swings within 100mV of the rails with a 2.5V to 5.5V supply. |
| 8 | V+ | power_in | Positive supply rail; the specified single-supply range is 2.7V to 5.5V (operating range 2.5V to 5.5V), and a 10µF ceramic bypass capacitor at this pin is the recommended minimum. |
