OPA991SIDBVR from Texas Instruments, in a SOT-23-6. 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 | output | Amplifier output. Rail-to-rail; can source/sink up to ±75 mA and drive up to 1 nF capacitive loads while maintaining stability. |
| 2 | V- | power_in | Negative (lowest) supply rail. Connect to ground for single-supply operation, or to the negative rail for split-supply operation. Total supply range 2.7 V to 40 V (V+ minus V-). |
| 3 | IN+ | input | Non-inverting input. Rail-to-rail common-mode input range extending 100 mV beyond both supply rails. Input bias current typically ±10 pA. |
| 4 | IN- | input | Inverting input. Rail-to-rail common-mode input range extending 100 mV beyond both supply rails. Input bias current typically ±10 pA. |
| 5 | SHDN | input | Active-high shutdown control. Logic low (< V- + 0.2 V) enables the amplifier; logic high (> V- + 1.1 V) disables the amplifier and drops supply current to ~30 µA. See section 7.3.11 for details. |
| 6 | V+ | power_in | Positive (highest) supply rail. Total supply range 2.7 V to 40 V (V+ minus V-). Bypass with 100 nF ceramic to V-. |
