Texas Instruments · Precision Op Amps · SOT-23-8
OPA2378AIDCNT from Texas Instruments, in a SOT-23-8. 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 | Out A | output | Channel A rail-to-rail output, which swings within 10mV of the supplies. |
| 2 | -In A | input | Channel A inverting input; input common-mode range extends 0.05V beyond the supply rails, and input current must be limited to 10mA if signals swing more than 0.3V beyond the rails. |
| 3 | +In A | input | Channel A non-inverting input; input common-mode range extends 0.05V beyond the supply rails, and input current must be limited to 10mA if signals swing more than 0.3V beyond the rails. |
| 4 | V- | power_in | Negative supply (ground in single-supply use); total supply voltage VS = (V+) - (V-) is 2.2V to 5.5V, with an absolute maximum of 7V. |
| 5 | +In B | input | Channel B non-inverting input; input common-mode range extends 0.05V beyond the supply rails, and input current must be limited to 10mA if signals swing more than 0.3V beyond the rails. |
| 6 | -In B | input | Channel B inverting input; input common-mode range extends 0.05V beyond the supply rails, and input current must be limited to 10mA if signals swing more than 0.3V beyond the rails. |
| 7 | Out B | output | Channel B rail-to-rail output, which swings within 10mV of the supplies. |
| 8 | V+ | power_in | Positive supply; total supply voltage VS = (V+) - (V-) is 2.2V to 5.5V, with an absolute maximum of 7V, and a 0.1µF capacitor should be placed closely across the supply pins. |
