Texas Instruments · Operational Amplifier · SOIC-8
OPA244UA from Texas Instruments, in a SOIC-8. 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 | NC | unconnected | Marked NC on the pinout drawing; the datasheet states no function or connection for this pin. |
| 2 | -In | input | Inverting input; the common-mode input range is 0 V to (V+) - 0.9 V, and inputs are diode-clamped to the supply rails and should be limited to 10 mA if they can exceed the rails by more than 0.3 V. |
| 3 | +In | input | Non-inverting input; the common-mode input range is 0 V to (V+) - 0.9 V, and inputs are diode-clamped to the supply rails and should be limited to 10 mA if they can exceed the rails by more than 0.3 V. |
| 4 | V- | power_in | Negative supply; the part runs from dual supplies of +/-1.1 V to +/-18 V or from a single supply of +2.2 V to +36 V, with the input range referenced to V-. |
| 5 | NC | unconnected | Marked NC on the pinout drawing; the datasheet states no function or connection for this pin. |
| 6 | Output | output | Amplifier output; short-circuit current is -25/+12 mA and the output may be shorted continuously to ground (one amplifier per package). |
| 7 | V+ | power_in | Positive supply; the specified supply range is +2.6 V to +36 V, the minimum operating voltage is +2.2 V, and the absolute maximum supply (V+ to V-) is 36 V. |
| 8 | NC | unconnected | Marked NC on the pinout drawing; the datasheet states no function or connection for this pin. |
