OPA191IDBVR 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 signal pin providing rail-to-rail buffered signal with voltage swing of 5-500mV offset from either supply rail depending on load resistance. |
| 2 | V- | power_in | Negative (lowest) power supply pin rated for operating voltage from ±2.25V to ±18V in dual-supply mode or 4.5V to 36V as (V+) − (V−) in single-supply mode. |
| 3 | +IN | input | Non-inverting input pin with common-mode voltage range from (V−) − 0.1V to (V+) + 0.1V and maximum input current of ±10mA. |
| 4 | -IN | input | Inverting input pin with common-mode voltage range from (V−) − 0.1V to (V+) + 0.1V and maximum input current of ±10mA. |
| 5 | V+ | power_in | Positive (highest) power supply pin rated for operating voltage from 4.5V to 36V single-supply (or ±2.25V to ±18V dual-supply) with absolute maximum 40V. |
