**Texas Instruments** · Operational Amplifier · TSSOP-14

OPA4727AIPWR from Texas Instruments, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT A | output | Output of amplifier A. Rail-to-rail-ish output swings within ~150 mV of the rails (100 kΩ load) and can source/sink up to 40 mA typical (±55 mA short-circuit). |
| 2 | -IN A | input | Inverting input of amplifier A. High-impedance CMOS input (10^11 Ω common-mode); input bias current ±500 pA max. |
| 3 | +IN A | input | Non-inverting input of amplifier A. Common-mode range extends from V- up to (V+) - 2.5 V for guaranteed CMRR. |
| 4 | V+ | power_in | Positive supply pin. Specified 4 V to 12 V (operating 3.5 V to 13.2 V); absolute maximum supply voltage 13.2 V. Bypass with a local 0.1 µF ceramic to V-. Quiescent current 4.3 mA typ per amplifier (≈17 mA total for quad). |
| 5 | +IN B | input | Non-inverting input of amplifier B. Same input structure as +IN A; common-mode range V- to (V+) - 2.5 V. |
| 6 | -IN B | input | Inverting input of amplifier B. High-impedance CMOS input; input bias current ±500 pA max. |
| 7 | OUT B | output | Output of amplifier B. Swings within ~150 mV of the rails into 100 kΩ; ±40 mA typical drive. |
| 8 | OUT C | output | Output of amplifier C. Swings within ~150 mV of the rails into 100 kΩ; ±40 mA typical drive. |
| 9 | -IN C | input | Inverting input of amplifier C. High-impedance CMOS input; input bias current ±500 pA max. |
| 10 | +IN C | input | Non-inverting input of amplifier C. Common-mode range V- to (V+) - 2.5 V. |
| 11 | V- | power_in | Negative supply pin. Tie to GND for single-supply operation (input common-mode range extends to GND) or to a negative rail for split supply (±2 V to ±6 V). Bypass with a local 0.1 µF ceramic to V+. |
| 12 | +IN D | input | Non-inverting input of amplifier D. Common-mode range V- to (V+) - 2.5 V. |
| 13 | -IN D | input | Inverting input of amplifier D. High-impedance CMOS input; input bias current ±500 pA max. |
| 14 | OUT D | output | Output of amplifier D. Swings within ~150 mV of the rails into 100 kΩ; ±40 mA typical drive. |
