OPA313IDCKR from Texas Instruments, in a SC-70-5. 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 | +IN | input | Non-inverting input of the rail-to-rail op amp; input common-mode range extends 200 mV beyond both supply rails and input current should be limited to 10 mA if it exceeds the rails by 0.5 V. |
| 2 | V- | power_in | Negative supply (ground in single-supply use); rated supply range is 1.8 V to 5.5 V (±0.9 V to ±2.75 V) between V+ and V-. |
| 3 | -IN | input | Inverting input of the rail-to-rail op amp; input pins are diode-clamped to the supply rails with a 10 mA maximum input current. |
| 4 | OUT | output | Rail-to-rail Class AB output that drives loads of 10 kΩ or less, with continuous short-circuit current of about ±15 mA at 5.5 V supply and stable up to about 1 nF capacitive load in unity gain. |
| 5 | V+ | power_in | Positive supply, 1.8 V to 5.5 V, which should be bypassed with a 0.01 µF ceramic capacitor (absolute maximum supply voltage 7 V). |
