TC913ACOA from Microchip Tech, 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, driven by the low-impedance class AB output buffer whose open-loop gain does not depend on load resistance. |
| 2 | -IN A | input | Inverting input of amplifier A; the common-mode voltage range is VSS to VDD - 2V. |
| 3 | +IN A | input | Non-inverting input of amplifier A; the common-mode voltage range is VSS to VDD - 2V. |
| 4 | VSS | power_in | Negative power supply; split supply is ±3.5V to ±8.3V and single supply is 7.0V to 16V (VDD to VSS). |
| 5 | +IN B | input | Non-inverting input of amplifier B; the common-mode voltage range is VSS to VDD - 2V. |
| 6 | -IN B | input | Inverting input of amplifier B; the common-mode voltage range is VSS to VDD - 2V. |
| 7 | OUT B | output | Output of amplifier B, driven by the low-impedance class AB output buffer whose open-loop gain does not depend on load resistance. |
| 8 | VDD | power_in | Positive power supply; split supply is ±3.5V to ±8.3V and single supply is 7.0V to 16V, with total supply voltage (VDD to VSS) not to exceed +18V. |
