LTC8631XT5

Linearin · Operational Amplifier · SOT-23-5L

LTC8631XT5 from Linearin, in a SOT-23-5L. 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 output Amplifier output, rail-to-rail, stable with capacitive loads up to 500 pF.
2 -VS power_in Negative power supply, normally tied to ground, and the voltage between VS+ and VS- must be 2.3 V to 5.5 V.
3 +IN input Non-inverting input of the amplifier, with a voltage range from (VS- - 0.1 V) to (VS+ + 0.1 V).
4 -IN input Inverting input of the amplifier, with a voltage range from (VS- - 0.1 V) to (VS+ + 0.1 V).
5 +VS power_in Positive power supply of 2.3 V to 5.5 V, and split supplies are allowed if VS+ to VS- is 2.3 V to 5.5 V.
