LT1490CS8#PBF

Analog Devices · Operational Amplifier · SO-8

LT1490CS8#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 rail-to-rail output that drives 20mA loads and is stable to 10,000pF with optional 0.22µF and 150Ω compensation.
2 -IN A input Amplifier A inverting input, which accepts 44V differential and common mode and is protected up to 22V below V- by an internal 1k series resistor.
3 +IN A input Amplifier A non-inverting input, which accepts 44V differential and common mode and is protected up to 22V below V- by an internal 1k series resistor.
4 V- power_in Negative supply (ground in single-supply use); total supply V+ to V- is 2V to 44V, and the inputs may sit 44V above V- regardless of V+.
5 +IN B input Amplifier B non-inverting input, which accepts 44V differential and common mode and is protected up to 22V below V- by an internal 1k series resistor.
6 -IN B input Amplifier B inverting input, which accepts 44V differential and common mode and is protected up to 22V below V- by an internal 1k series resistor.
7 OUT B output Amplifier B rail-to-rail output that drives 20mA loads and is stable to 10,000pF with optional 0.22µF and 150Ω compensation.
8 V+ power_in Positive supply, bypassed with about 0.01µF within an inch of the pin, protected against reverse battery up to 18V, with a 44V maximum total supply.
