# OPA316IDCKR

**Texas Instruments** · Operational Amplifier · SC-70-5

OPA316IDCKR 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; the common-mode range extends from (V-) - 0.2 V to (V+) + 0.2 V for a 2.5 V to 5.5 V supply, and signal input pins are absolutely limited to (V-) - 0.5 V to (V+) + 0.5 V with input current limited to ±10 mA. |
| 2 | V- | power_in | Negative power supply, or ground for single-supply operation, with the total supply voltage (V+) - (V-) rated 1.8 V to 5.5 V in operation and 7 V absolute maximum. |
| 3 | -IN | input | Inverting input; the common-mode range extends from (V-) - 0.2 V to (V+) + 0.2 V for a 2.5 V to 5.5 V supply, and signal input pins are absolutely limited to (V-) - 0.5 V to (V+) + 0.5 V with input current limited to ±10 mA. |
| 4 | OUT | output | Rail-to-rail output that swings within about 30 mV of the supply rails with a 10 kΩ load, and the datasheet rates the output short-circuit to ground as continuous. |
| 5 | V+ | power_in | Positive power supply, rated 1.8 V to 5.5 V in operation with a 7 V absolute maximum supply voltage. |
