LTC8581XS8

Linearin(先积集成) · IC · SOIC-8L

LTC8581XS8 from Linearin(先积集成), 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 NC unconnected No internal connection.
2 -IN input Inverting input of the amplifier; input common-mode range extends 100 mV below the negative supply to the positive supply.
3 +IN input Non-inverting input of the amplifier; input common-mode range extends 100 mV below the negative supply to the positive supply.
4 -VS power_in Negative (lowest) power supply.
5 NC unconnected No internal connection.
6 OUT output Amplifier output with rail-to-rail swing and short-circuit current of ±45 mA typical.
7 +VS power_in Positive (highest) power supply, 1.8 V to 5.5 V operating range (2.0 V to 5.5 V over -40 to +125 °C), 10 V absolute maximum between supplies.
8 NC unconnected No internal connection.
