# OPA358AIDCKR

**Texas Instruments** · Operational Amplifier · SC-70-6

OPA358AIDCKR from Texas Instruments, in a SC-70-6. 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 | V+ | power_in | Positive power supply; specified range 2.7V to 3.3V (operating range 2.5V to 3.6V); bypass with 100nF ceramic capacitor to ground. |
| 2 | Enable | input | Shutdown enable control input; logic HIGH (≥1.6V) enables amplifier, logic LOW (≤0.8V) disables output; internal pull-up to V+. |
| 3 | Out | output | Output terminal; at +3.3V with AOL > 84dB output swings (V−) + 100mV to (V+) − 200mV with ±50mA output current capability. |
| 4 | −In | input | Inverting input terminal; common-mode range (V−) − 0.1V to (V+) − 1.0V; input diode-clamped to supply rails with external current limiting to 10mA maximum for overdrive protection. |
| 5 | GND | power_in | Power supply ground (negative rail); bypass with 100nF ceramic capacitor to V+. |
| 6 | +In | input | Non-inverting input terminal; common-mode range (V−) − 0.1V to (V+) − 1.0V; input diode-clamped to supply rails with external current limiting to 10mA maximum for overdrive protection. |
