OPA314AIDBVR from Texas Instruments, in a SOT-23-5. 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 output stage capable of swinging close to both supply rails; short-circuit current limited (see Absolute Maximum Ratings, output short-circuit continuous, one amplifier per package). |
| 2 | V- | power_in | Negative (lowest) supply rail. For single-supply operation tie to GND; for dual-supply operation connect to the negative rail. Total supply span V+ to V- must be 1.8V to 5.5V. |
| 3 | +IN | input | Noninverting input. Rail-to-rail CMOS input; ultra-low input bias current (0.2pA typical). Input voltage must remain within (V-)-0.5V to (V+)+0.5V absolute max; input current limited to +/-10mA via internal ESD diode clamps. |
| 4 | -IN | input | Inverting input. Rail-to-rail CMOS input; ultra-low input bias current (0.2pA typical). Input voltage must remain within (V-)-0.5V to (V+)+0.5V absolute max; input current limited to +/-10mA via internal ESD diode clamps. |
| 5 | V+ | power_in | Positive (highest) supply rail. Operating range 1.8V to 5.5V referenced to V-. Bypass with a 0.1uF ceramic capacitor close to the pin. |
