OPA2335AIDR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Channel A op-amp output. Rail-to-rail CMOS output stage capable of driving to within millivolts of V+ and V−. |
| 2 | -INA | input | Channel A inverting input. High-impedance CMOS input, diode-clamped to the supply rails; input signals beyond V±0.5 V should be current-limited to ≤10 mA. |
| 3 | +INA | input | Channel A non-inverting input. High-impedance CMOS input, common-mode range extends to V− (rail-to-rail input on the negative rail); diode-clamped to the supply rails. |
| 4 | V- | power_in | Negative supply / ground pin. Connect to 0 V for single-supply operation, or to −1.35 V to −2.75 V for split-supply operation. Total supply (V+ − V−) must not exceed 7 V absolute max. |
| 5 | +INB | input | Channel B non-inverting input. High-impedance CMOS input, common-mode range extends to V−; diode-clamped to the supply rails. |
| 6 | -INB | input | Channel B inverting input. High-impedance CMOS input, diode-clamped to the supply rails; input signals beyond V±0.5 V should be current-limited to ≤10 mA. |
| 7 | OUTB | output | Channel B op-amp output. Rail-to-rail CMOS output stage capable of driving to within millivolts of V+ and V−. |
| 8 | V+ | power_in | Positive supply pin. Operating range +2.7 V to +5.5 V single-supply (or ±1.35 V to ±2.75 V split-supply). Absolute maximum total supply +7 V. Bypass with a 0.1 µF ceramic capacitor to V−. |
