OPA2188AIDGKR from Texas Instruments, in a VSSOP-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; the output limits into the appropriate supply rail when the input is driven beyond its common-mode range (phase-reversal protection, page 18). |
| 2 | -IN A | input | Negative (inverting) input signal for channel A. |
| 3 | +IN A | input | Positive (noninverting) input signal for channel A; the input common-mode range includes the negative supply rail (V-). |
| 4 | V- | power_in | Negative (lowest) power supply; the device operates from 4 V to 36 V total supply (±2 V to ±18 V) per the recommended operating conditions. |
| 5 | +IN B | input | Positive (noninverting) input signal for channel B; the input common-mode range includes the negative supply rail (V-). |
| 6 | -IN B | input | Negative (inverting) input signal for channel B. |
| 7 | OUT B | output | Output of channel B; the output limits into the appropriate supply rail when the input is driven beyond its common-mode range (phase-reversal protection, page 18). |
| 8 | V+ | power_in | Positive (highest) power supply; the device operates from 4 V to 36 V total supply (±2 V to ±18 V) per the recommended operating conditions. |
