OPA2301AID from Texas Instruments, 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 | Amplifier A output, rail-to-rail class AB swinging typically within 100mV of the supplies with a 2kΩ load. |
| 2 | -In A | input | Amplifier A inverting input, diode clamped to the supply rails and to be current limited to 10mA if it swings more than 0.5V beyond them. |
| 3 | +In A | input | Amplifier A non-inverting input, diode clamped to the supply rails and to be current limited to 10mA if it swings more than 0.5V beyond them. |
| 4 | V− | power_in | Negative supply (ground in single-supply use) for both amplifiers. |
| 5 | +In B | input | Amplifier B non-inverting input, diode clamped to the supply rails and to be current limited to 10mA if it swings more than 0.5V beyond them. |
| 6 | -In B | input | Amplifier B inverting input, diode clamped to the supply rails and to be current limited to 10mA if it swings more than 0.5V beyond them. |
| 7 | Out B | output | Amplifier B output, rail-to-rail class AB swinging typically within 100mV of the supplies with a 2kΩ load. |
| 8 | V+ | power_in | Positive supply, specified from 2.7V to 5.5V with an absolute maximum of 7V. |
