**Texas Instruments** · Operational Amplifier · VSSOP-8

TLV2314IDGKR from Texas Instruments, in a VSSOP-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, which in the AB-class output stage stays within about 5 mV of the supply rails with a 10 kΩ load and has a typical short-circuit current of ±20 mA. |
| 2 | -IN A | input | Channel A inverting input, whose common-mode range extends 200 mV beyond each supply rail (VCM = (V-) - 0.2 V to (V+) + 0.2 V at 25°C). |
| 3 | +IN A | input | Channel A non-inverting input, which is protected by internal diodes to the supply rails and should be limited to 10 mA if the signal exceeds a rail by more than 0.5 V. |
| 4 | V- | power_in | Negative (lowest) power supply, used with single supplies from 1.8 V to 5.5 V or dual supplies from ±0.9 V to ±2.75 V, with a 7 V absolute maximum supply rating. |
| 5 | +IN B | input | Channel B non-inverting input, which is protected by internal diodes to the supply rails and should be limited to 10 mA if the signal exceeds a rail by more than 0.5 V. |
| 6 | -IN B | input | Channel B inverting input, whose common-mode range extends 200 mV beyond each supply rail (VCM = (V-) - 0.2 V to (V+) + 0.2 V at 25°C). |
| 7 | OUT B | output | Channel B output, which in the AB-class output stage stays within about 5 mV of the supply rails with a 10 kΩ load and has a typical short-circuit current of ±20 mA. |
| 8 | V+ | power_in | Positive (highest) power supply, operated from 1.8 V to 5.5 V with a 7 V absolute maximum, where a 0.1 µF bypass capacitor placed near the pin is recommended. |
