# OPA2348AIDCNT

**Texas Instruments** · Operational Amplifier · SOT-23-8

OPA2348AIDCNT 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 | Output terminal for Channel A with rail-to-rail swing from V- to V+ within 18-25 mV of rails depending on load resistance. |
| 2 | -IN A | input | Inverting input for Channel A; common-mode input voltage range extends from (V-) - 0.2V to (V+) + 0.2V. |
| 3 | +IN A | input | Non-inverting input for Channel A; common-mode input voltage range extends from (V-) - 0.2V to (V+) + 0.2V. |
| 4 | V- | power_in | Negative power supply terminal at lowest potential; typical 0V (single supply) or negative rail in dual supply. |
| 5 | +IN B | input | Non-inverting input for Channel B; common-mode input voltage range extends from (V-) - 0.2V to (V+) + 0.2V. |
| 6 | -IN B | input | Inverting input for Channel B; common-mode input voltage range extends from (V-) - 0.2V to (V+) + 0.2V. |
| 7 | OUT B | output | Output terminal for Channel B with rail-to-rail swing from V- to V+ within 18-25 mV of rails depending on load resistance. |
| 8 | V+ | power_in | Positive power supply terminal at highest potential; supply voltage range 2.1V to 5.5V per specifications. |
