# LMC6492BEMX

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

LMC6492BEMX from Texas Instruments, in a SOIC-8-EP. 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; the output current is limited to ±30 mA absolute maximum, and sustained operation beyond ±30 mA impairs reliability. |
| 2 | -IN A | input | Inverting input of amplifier A; when the input is driven beyond the supply rails, the input current must be limited externally to ±5 mA. |
| 3 | +IN A | input | Non-inverting input of amplifier A; the rail-to-rail input common-mode range extends beyond both supply rails. |
| 4 | V- | power_in | Negative power supply voltage input; the supply voltage VS = (V+) - (V-) is specified at 2.5 V to 15.5 V. |
| 5 | +IN B | input | Non-inverting input of amplifier B; the rail-to-rail input common-mode range extends beyond both supply rails. |
| 6 | -IN B | input | Inverting input of amplifier B; when the input is driven beyond the supply rails, the input current must be limited externally to ±5 mA. |
| 7 | OUT B | output | Output of amplifier B; the output current is limited to ±30 mA absolute maximum, and sustained operation beyond ±30 mA impairs reliability. |
| 8 | V+ | power_in | Positive power supply voltage input; the supply voltage VS = (V+) - (V-) is specified at 2.5 V to 15.5 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
