Texas Instruments · Operational Amplifier · SOT-23-5
OPA991QDBVRQ1 from Texas Instruments, in a SOT-23-5. 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 | output | Output: Provides the amplified signal from the operational amplifier |
| 2 | V- | power_in | Negative (lowest) power supply; common mode input range extends from (V-) - 0.1V to (V+) + 0.1V |
| 3 | IN+ | input | Non-inverting input; accepts signals within the common mode voltage range of (V-) - 0.1V to (V+) + 0.1V |
| 4 | IN- | input | Inverting input; accepts signals within the common mode voltage range of (V-) - 0.1V to (V+) + 0.1V |
| 5 | V+ | power_in | Positive (highest) power supply; supply voltage range VS = (V+) - (V-) from 2.7V to 40V (±1.35V to ±20V) |
