LT1638CS8#PBF

Analog Devices · Operational Amplifier · SO-8

LT1638CS8#PBF from Analog Devices, in a SO-8. 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 Amplifier A output, rail-to-rail, drives loads up to 25mA min and capacitive loads up to 200pF (1000pF with optional output compensation).
2 -IN A input Amplifier A inverting input, rail-to-rail with over-the-top operation up to 44V above V- and 44V maximum differential input voltage.
3 +IN A input Amplifier A non-inverting input, rail-to-rail with over-the-top operation up to 44V above V- and 44V maximum differential input voltage.
4 V- power_in Negative supply (ground in single-supply use); total supply V+ to V- is 2.5V to 44V and it should be bypassed with 0.1uF when using split supplies.
5 +IN B input Amplifier B non-inverting input, rail-to-rail with over-the-top operation up to 44V above V- and 44V maximum differential input voltage.
6 -IN B input Amplifier B inverting input, rail-to-rail with over-the-top operation up to 44V above V- and 44V maximum differential input voltage.
7 OUT B output Amplifier B output, rail-to-rail, drives loads up to 25mA min and capacitive loads up to 200pF (1000pF with optional output compensation).
8 V+ power_in Positive supply, reverse-battery protected to 18V and should be bypassed with 0.1uF within an inch of the pin; total supply V+ to V- is 2.5V to 44V.
