LTC8581XT5

Linearin(先积集成) · Operational Amplifier · SOT23-5L

LTC8581XT5 from Linearin(先积集成), in a SOT23-5L. 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; the datasheet states the output short-circuit condition is continuous and its absolute maximum rating is listed as continuous.
2 -VS power_in Negative (lowest) power supply; the device is specified from 1.8 V to 5.5 V total supply, and VS+ to VS- must not exceed 10.0 V absolute maximum.
3 +IN input Non-inverting input; the common-mode range extends 100 mV beyond the negative rail and reaches the positive rail, and signal inputs are limited to VS- - 0.3 V to VS+ + 0.3 V and ±10 mA.
4 -IN input Inverting input of the amplifier; signal inputs are limited to VS- - 0.3 V to VS+ + 0.3 V and ±10 mA.
5 +VS power_in Positive (highest) power supply; the device is specified from 1.8 V to 5.5 V total supply, and VS+ to VS- must not exceed 10.0 V absolute maximum.
