# LMC6494BEMX

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

LMC6494BEMX 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 | OUT A | output | Output of amplifier A, which swings within about 100 mV of the supply rails with a 2 kΩ load. |
| 2 | -IN A | input | Inverting input of amplifier A. |
| 3 | +IN A | input | Non-inverting input of amplifier A; the common-mode range extends beyond both supply rails. |
| 4 | V+ | power_in | Positive power supply input; the recommended total supply VS = (V+) − (V−) is 2.5 V to 15.5 V. |
| 5 | +IN B | input | Non-inverting input of amplifier B; the common-mode range extends beyond both supply rails. |
| 6 | -IN B | input | Inverting input of amplifier B. |
| 7 | OUT B | output | Output of amplifier B, which swings within about 100 mV of the supply rails with a 2 kΩ load. |
| 8 | OUT C | output | Output of amplifier C, which swings within about 100 mV of the supply rails with a 2 kΩ load. |
| 9 | -IN C | input | Inverting input of amplifier C. |
| 10 | +IN C | input | Non-inverting input of amplifier C; the common-mode range extends beyond both supply rails. |
| 11 | V- | power_in | Negative power supply input; the recommended total supply VS = (V+) − (V−) is 2.5 V to 15.5 V. |
| 12 | +IN D | input | Non-inverting input of amplifier D; the common-mode range extends beyond both supply rails. |
| 13 | -IN D | input | Inverting input of amplifier D. |
| 14 | OUT D | output | Output of amplifier D, which swings within about 100 mV of the supply rails with a 2 kΩ load. |
