OPA2172IDR 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 | OUT A | output | Output of channel A op-amp. Rail-to-rail output stage; can swing within ~100 mV of either supply rail with typical loads. |
| 2 | -IN A | input | Inverting input of channel A. Input bias current typ. ±8 pA; input range includes the negative supply and operates to the positive supply. |
| 3 | +IN A | input | Noninverting input of channel A. High-impedance CMOS input; input range includes V- and operates to V+. |
| 4 | V- | power_in | Negative (lowest) power supply. Connect to ground for single-supply operation or to the negative rail for split-supply operation. Total supply range +4.5 V to +36 V (V+ - V-). |
| 5 | +IN B | input | Noninverting input of channel B. High-impedance CMOS input; input range includes V- and operates to V+. |
| 6 | -IN B | input | Inverting input of channel B. Input bias current typ. ±8 pA. |
| 7 | OUT B | output | Output of channel B op-amp. Rail-to-rail output stage. |
| 8 | V+ | power_in | Positive (highest) power supply. Bypass to V- with a low-ESR ceramic capacitor close to the pin. Total supply range +4.5 V to +36 V. |
