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

TLC27M4BCDR from Texas Instruments, in a SOIC-14. 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 | 1OUT | output | Output of amplifier 1; the output may be shorted to either supply indefinitely at 25°C or below, provided temperature and supply voltage are limited so the maximum power dissipation is not exceeded. |
| 2 | 1IN- | input | Inverting input of amplifier 1; the input voltage must stay within the absolute maximum range of -0.3 V to VDD. |
| 3 | 1IN+ | input | Non-inverting input of amplifier 1; the recommended common-mode input range is -0.2 V to 3.5 V at VDD = 5 V and -0.2 V to 8.5 V at VDD = 10 V for the C and I grades. |
| 4 | VDD | power_in | Positive supply; recommended 3 V to 16 V for 0°C to 70°C and 4 V to 16 V for -40°C to 85°C and -55°C to 125°C, with an absolute maximum of 18 V. |
| 5 | 2IN+ | input | Non-inverting input of amplifier 2; the recommended common-mode input range is -0.2 V to 3.5 V at VDD = 5 V and -0.2 V to 8.5 V at VDD = 10 V for the C and I grades. |
| 6 | 2IN- | input | Inverting input of amplifier 2; the input voltage must stay within the absolute maximum range of -0.3 V to VDD. |
| 7 | 2OUT | output | Output of amplifier 2; the output may be shorted to either supply indefinitely at 25°C or below, provided temperature and supply voltage are limited so the maximum power dissipation is not exceeded. |
| 8 | 3OUT | output | Output of amplifier 3; the output may be shorted to either supply indefinitely at 25°C or below, provided temperature and supply voltage are limited so the maximum power dissipation is not exceeded. |
| 9 | 3IN- | input | Inverting input of amplifier 3; the input voltage must stay within the absolute maximum range of -0.3 V to VDD. |
| 10 | 3IN+ | input | Non-inverting input of amplifier 3; the recommended common-mode input range is -0.2 V to 3.5 V at VDD = 5 V and -0.2 V to 8.5 V at VDD = 10 V for the C and I grades. |
| 11 | GND | power_in | Ground or negative supply; all voltages are referenced to network ground. |
| 12 | 4IN+ | input | Non-inverting input of amplifier 4; the recommended common-mode input range is -0.2 V to 3.5 V at VDD = 5 V and -0.2 V to 8.5 V at VDD = 10 V for the C and I grades. |
| 13 | 4IN- | input | Inverting input of amplifier 4; the input voltage must stay within the absolute maximum range of -0.3 V to VDD. |
| 14 | 4OUT | output | Output of amplifier 4; the output may be shorted to either supply indefinitely at 25°C or below, provided temperature and supply voltage are limited so the maximum power dissipation is not exceeded. |
