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

TLC2274CPWR 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 | 1OUT | output | Output of op-amp channel 1. Rail-to-rail output stage; can source/sink up to ±50 mA (absolute max). |
| 2 | 1IN- | input | Inverting input of op-amp channel 1. High-impedance CMOS input; typical input bias current 1 pA. |
| 3 | 1IN+ | input | Non-inverting input of op-amp channel 1. Common-mode input range extends to the negative supply rail. |
| 4 | VDD+ | power_in | Positive (highest) supply rail. Operating range ±2.2 V to ±8 V split, or 4.4 V to 16 V single-supply (referenced to VDD-). Absolute maximum 8 V above VDD-. |
| 5 | 2IN+ | input | Non-inverting input of op-amp channel 2. Common-mode input range extends to the negative supply rail. |
| 6 | 2IN- | input | Inverting input of op-amp channel 2. High-impedance CMOS input; typical input bias current 1 pA. |
| 7 | 2OUT | output | Output of op-amp channel 2. Rail-to-rail output stage; can source/sink up to ±50 mA (absolute max). |
| 8 | 3OUT | output | Output of op-amp channel 3. Rail-to-rail output stage; can source/sink up to ±50 mA (absolute max). |
| 9 | 3IN- | input | Inverting input of op-amp channel 3. High-impedance CMOS input; typical input bias current 1 pA. |
| 10 | 3IN+ | input | Non-inverting input of op-amp channel 3. Common-mode input range extends to the negative supply rail. |
| 11 | VDD- | power_in | Negative (lowest) supply rail. Tie to GND for single-supply operation. Absolute maximum -8 V referenced to VDD+. |
| 12 | 4IN+ | input | Non-inverting input of op-amp channel 4. Common-mode input range extends to the negative supply rail. |
| 13 | 4IN- | input | Inverting input of op-amp channel 4. High-impedance CMOS input; typical input bias current 1 pA. |
| 14 | 4OUT | output | Output of op-amp channel 4. Rail-to-rail output stage; can source/sink up to ±50 mA (absolute max). |
