# OPA317IDCKR

**Texas Instruments** · Precision Op Amps · SC-70-5

OPA317IDCKR 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 | Noninverting input; the common-mode input range extends 0.1 V beyond the supply rails, and input signals that exceed the rails by 0.3 V or more must be current-limited to 10 mA or less. |
| 2 | V- | power_in | Negative (lowest) power supply; the supply range is 1.8 V (±0.9 V) to 5.5 V (±2.75 V) across V+ and V-. |
| 3 | -IN | input | Inverting input; the common-mode input range extends 0.1 V beyond the supply rails, and input signals that exceed the rails by 0.3 V or more must be current-limited to 10 mA or less. |
| 4 | OUT | output | Output; the class AB output stage drives loads of 10 kΩ or less connected to any point between V+ and ground. |
| 5 | V+ | power_in | Positive (highest) power supply; supply voltages above 7 V can permanently damage the device. |
