OPA2990IDSGR from Texas Instruments, in a WSON-8-EP(2x2). 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 | OUT1 | output | Output, channel 1; DC output with rail-to-rail swing capability within specified voltage margins per supply voltage (45-300mV at 40V, 5-50mV at 2.7V). |
| 2 | IN1- | input | Inverting input, channel 1; accepts differential input signals within common-mode range (V-)−0.2V to (V+)+0.2V. |
| 3 | IN1+ | input | Non-inverting input, channel 1; accepts differential input signals within common-mode range (V-)−0.2V to (V+)+0.2V. |
| 4 | V- | power_in | Negative (lowest) power supply rail; establishes analog ground reference and completes output current return path; typical supply range 2.7V to 40V above absolute minimum. |
| 5 | IN2+ | input | Non-inverting input, channel 2; accepts differential input signals within common-mode range (V-)−0.2V to (V+)+0.2V. |
| 6 | IN2- | input | Inverting input, channel 2; accepts differential input signals within common-mode range (V-)−0.2V to (V+)+0.2V. |
| 7 | OUT2 | output | Output, channel 2; DC output with rail-to-rail swing capability within specified voltage margins per supply voltage (45-300mV at 40V, 5-50mV at 2.7V). |
| 8 | V+ | power_in | Positive (highest) power supply rail; provides bias current and enables output stage amplification; typical supply range 2.7V to 40V above V-. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
