LT6221IS8#TRPBF

Analog Devices · Operational Amplifier · SO-8

LT6221IS8#TRPBF 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 Output of amplifier A, which swings within 10mV of either supply rail.
2 -IN A input Inverting input of amplifier A; the inputs can be driven beyond the supplies without damage or phase reversal of the output.
3 +IN A input Non-inverting input of amplifier A; the input range includes both supply rails.
4 VS- power_in Negative supply rail, operating from 2.2V to 12.6V total supply.
5 +IN B input Non-inverting input of amplifier B; the input range includes both supply rails.
6 -IN B input Inverting input of amplifier B; the inputs can be driven beyond the supplies without damage or phase reversal of the output.
7 OUT B output Output of amplifier B, which swings within 10mV of either supply rail.
8 VS+ power_in Positive supply rail, operating from 2.2V to 12.6V total supply.
