OPA2188AIDR 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 | Channel A op-amp output. Rail-to-rail output stage; drives up to ±18 mA short-circuit current with output swing to within ~250 mV of the rails at 10 kΩ load. |
| 2 | -IN A | input | Channel A inverting input. High-impedance CMOS input (100 MΩ |
| 3 | +IN A | input | Channel A non-inverting input. Common-mode range extends from V- to (V+)-1.5 V; input bias current ±160 pA typical. |
| 4 | V- | power_in | Negative supply rail. Connect to ground for single-supply operation or to the negative rail for split supply. Total supply range 4 V to 36 V (±2 V to ±18 V). |
| 5 | +IN B | input | Channel B non-inverting input. Common-mode range extends from V- to (V+)-1.5 V; input bias current ±160 pA typical. |
| 6 | -IN B | input | Channel B inverting input. High-impedance CMOS input (100 MΩ |
| 7 | OUT B | output | Channel B op-amp output. Rail-to-rail output stage; drives up to ±18 mA short-circuit current with output swing to within ~250 mV of the rails at 10 kΩ load. |
| 8 | V+ | power_in | Positive supply rail. Bypass with 100 nF close to the pin. Total supply range 4 V to 36 V (±2 V to ±18 V); quiescent current 475 µA maximum per amplifier. |
