# OPA2374AIDCNR

**Texas Instruments** · Precision Op Amps · SOT-23-8

OPA2374AIDCNR 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 output; with a light load (>100 kΩ) it swings to within about 18 mV of the supply rails, and with 5 kΩ to 50 kΩ it swings to within about 100 mV. |
| 2 | -IN A | input | Channel A inverting input; for normal operation the input must stay within the common-mode range (V-) - 0.2 V to (V+) + 0.2 V. |
| 3 | +IN A | input | Channel A non-inverting input; for normal operation the input must stay within the common-mode range (V-) - 0.2 V to (V+) + 0.2 V. |
| 4 | V- | power_in | Negative (lowest) power supply pin. |
| 5 | +IN B | input | Channel B non-inverting input; for normal operation the input must stay within the common-mode range (V-) - 0.2 V to (V+) + 0.2 V. |
| 6 | -IN B | input | Channel B inverting input; for normal operation the input must stay within the common-mode range (V-) - 0.2 V to (V+) + 0.2 V. |
| 7 | OUT B | output | Channel B output; with a light load (>100 kΩ) it swings to within about 18 mV of the supply rails, and with 5 kΩ to 50 kΩ it swings to within about 100 mV. |
| 8 | V+ | power_in | Positive (highest) power supply pin; the rated supply range is 2.7 V to 5.5 V, with an absolute maximum of 7 V. |
