OPA2330AID 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 | Output of channel A. |
| 2 | -IN A | input | Negative (inverting) input signal of channel A, which is diode-clamped to the supply rails and should be current limited to 10 mA if signals swing more than 0.3 V beyond them. |
| 3 | +IN A | input | Positive (noninverting) input signal of channel A, which is diode-clamped to the supply rails and should be current limited to 10 mA if signals swing more than 0.3 V beyond them. |
| 4 | V- | power_in | Negative (lowest) power supply, with total supply voltage V+ to V- of 1.8 V to 5.5 V (±0.9 V to ±2.75 V). |
| 5 | +IN B | input | Positive (noninverting) input signal of channel B, which is diode-clamped to the supply rails and should be current limited to 10 mA if signals swing more than 0.3 V beyond them. |
| 6 | -IN B | input | Negative (inverting) input signal of channel B, which is diode-clamped to the supply rails and should be current limited to 10 mA if signals swing more than 0.3 V beyond them. |
| 7 | OUT B | output | Output of channel B. |
| 8 | V+ | power_in | Positive (highest) power supply, with total supply voltage V+ to V- of 1.8 V to 5.5 V (±0.9 V to ±2.75 V) and 7 V absolute maximum. |
