# LMC6442AIMX

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

LMC6442AIMX from Texas Instruments, in a SOIC-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 | Amplifier A output with rail-to-rail swing, output swing within 30 mV of the supply rail (typical, VS = 2.2V). |
| 2 | -IN A | input | Amplifier A inverting input, with input bias current of 5 fA typical and absolute maximum input pin current of ±5 mA. |
| 3 | +IN A | input | Amplifier A non-inverting input, with common-mode range from -0.3V to V+ - 0.9V and absolute maximum input pin current of ±5 mA. |
| 4 | V- | power_in | Negative supply pin (ground in single-supply operation), with total supply V+ - V- limited to 16V absolute maximum. |
| 5 | +IN B | input | Amplifier B non-inverting input, with common-mode range from -0.3V to V+ - 0.9V and absolute maximum input pin current of ±5 mA. |
| 6 | -IN B | input | Amplifier B inverting input, with input bias current of 5 fA typical and absolute maximum input pin current of ±5 mA. |
| 7 | OUT B | output | Amplifier B output with rail-to-rail swing, output swing within 30 mV of the supply rail (typical, VS = 2.2V). |
| 8 | V+ | power_in | Positive supply pin, operating range 1.8V to 11V and 16V absolute maximum between V+ and V-. |
