LTC722XF8

Linearin · Operational Amplifier · DFN-8-EP(2x2)

LTC722XF8 from Linearin, in a DFN-8-EP(2x2). 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 OUTA output Amplifier A output.
2 -INA input Inverting input of amplifier A; voltage range is from (VS- - 0.1V) to (VS+ + 0.1V).
3 +INA input Non-inverting input of amplifier A; same voltage range as -IN, (VS- - 0.1V) to (VS+ + 0.1V).
4 -VS power_in Negative power supply, normally tied to ground; may be tied to another voltage as long as VS+ to VS- is 2.0V to 5.5V.
5 +INB input Non-inverting input of amplifier B; same voltage range as -IN, (VS- - 0.1V) to (VS+ + 0.1V).
6 -INB input Inverting input of amplifier B; voltage range is from (VS- - 0.1V) to (VS+ + 0.1V).
7 OUTB output Amplifier B output.
8 +VS power_in Positive power supply, 2.0V to 5.5V; split supplies are possible as long as VS+ to VS- is 2.0V to 5.5V.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
