OPA2378AIDCNR 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 swinging within 10mV of the supplies, with continuous short-circuit to ground (one amplifier per package). |
| 2 | -In A | input | Channel A inverting input with internal EMI filter, diode-clamped to the supply rails; 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 with internal EMI filter, diode-clamped to the supply rails; common-mode range extends 0.05V beyond the supply rails and input current must be limited to 10mA. |
| 4 | V- | power_in | Negative supply (or ground in single-supply use); total supply VS = (V+) - (V-) is 2.2V to 5.5V with absolute maximum of 7V. |
| 5 | +In B | input | Channel B non-inverting input with internal EMI filter, diode-clamped to the supply rails; common-mode range extends 0.05V beyond the supply rails and input current must be limited to 10mA. |
| 6 | -In B | input | Channel B inverting input with internal EMI filter, diode-clamped to the supply rails; 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 swinging within 10mV of the supplies, with continuous short-circuit to ground (one amplifier per package). |
| 8 | V+ | power_in | Positive supply; total supply VS = (V+) - (V-) is 2.2V to 5.5V with absolute maximum of 7V, with a 0.1uF capacitor recommended closely across the supply pins. |
