LTC8542XS8 from Linearin, in a SOIC-8L. 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 | OUTA | output | Amplifier A output. |
| 2 | -INA | input | Amplifier A inverting input; voltage range is from (VS- - 0.1V) to (VS+ + 0.1V). |
| 3 | +INA | input | Amplifier A non-inverting input; same voltage range as -IN, (VS- - 0.1V) to (VS+ + 0.1V). |
| 4 | -VS | power_in | Negative power supply; supply voltage VS+ to VS- must not exceed 10.0 V absolute maximum. |
| 5 | +INB | input | Amplifier B non-inverting input; same voltage range as -IN, (VS- - 0.1V) to (VS+ + 0.1V). |
| 6 | -INB | input | Amplifier B inverting input; voltage range is from (VS- - 0.1V) to (VS+ + 0.1V). |
| 7 | OUTB | output | Amplifier B output. |
| 8 | +VS | power_in | Positive power supply; operates 1.8 V to 5.5 V at 0 to 70 °C and 2.0 V to 5.5 V at -40 to +125 °C. |
