MAX9943AUA+

Maxim Integrated · Pre-ordered Chips · MSOP-8

MAX9943AUA+ from Maxim Integrated, in a MSOP-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 N.C. unconnected No connection; this pin is not connected internally on the 8-pin µMAX package.
2 IN- input Negative (inverting) input of the amplifier, which the datasheet protects from excessive differential voltage with internal back-to-back diodes and series resistors.
3 IN+ input Positive (non-inverting) input of the amplifier; the input common-mode range extends to the negative supply VEE, with bias current increasing between VEE and VEE + 0.3V.
4 VEE power_in Negative power supply, bypassed with a 0.1µF capacitor to ground; single-supply operation uses VEE at ground.
5 N.C. unconnected No connection; this pin is not connected internally on the 8-pin µMAX package.
6 OUT output Amplifier output, which can swing to both VCC and VEE rails when lightly loaded and deliver up to 20mA of current.
7 VCC power_in Positive power supply, bypassed with a 0.1µF capacitor to ground; supply range is ±3V to ±19V dual or 6V to 38V single.
8 N.C. unconnected No connection; this pin is not connected internally on the 8-pin µMAX package.
