# OPA2725AIDGKT

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

OPA2725AIDGKT 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 | Output of amplifier A, which swings to within 175mV of the supply rails for light loads (>100kΩ) and within 250mV with 1kΩ loads (2kΩ for dual). |
| 2 | -IN A | input | Inverting input of amplifier A; the common-mode input range extends from V− to (V+) − 2V. |
| 3 | +IN A | input | Non-inverting input of amplifier A; the common-mode input range extends from V− to (V+) − 2V. |
| 4 | V− | power_in | Negative supply rail; the device operates from single supplies of 4V to 12V or dual supplies of ±2V to ±6V. |
| 5 | +IN B | input | Non-inverting input of amplifier B; the common-mode input range extends from V− to (V+) − 2V. |
| 6 | -IN B | input | Inverting input of amplifier B; the common-mode input range extends from V− to (V+) − 2V. |
| 7 | OUT B | output | Output of amplifier B, which swings to within 175mV of the supply rails for light loads (>100kΩ) and within 250mV with 2kΩ loads. |
| 8 | V+ | power_in | Positive supply rail; the device operates from single supplies of 4V to 12V or dual supplies of ±2V to ±6V. |
