MAX9922EUB+

Maxim Integrated · Precision OpAmps · MSOP-10

MAX9922EUB+ from Maxim Integrated, in a MSOP-10. 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 RSB power_in Current-sense amplifier input stage supply; connect to either RS+ or RS-.
2 RS+ input Current-sense amplifier positive input, with an input common-mode range of 1.9V to 28V that is independent of VDD.
3 RS- input Current-sense amplifier negative input, which forms the differential sense voltage VSENSE = VRS+ - VRS- with RS+.
4 N.C. unconnected No connection; the pin is not internally connected.
5 GND power_in Ground reference for the device.
6 SHDN input Shutdown logic input that must be connected to VDD for normal operation and to GND to reduce quiescent current to 1µA; logic-low maximum is 0.3V and logic-high minimum is 0.6 x VDD at VDD = 5.5V.
7 REF input Reference voltage input that is connected to GND for unidirectional operation or to an external voltage (VDD/2 for maximum dynamic range) for bidirectional output, with a guaranteed input range of 0 to VDD - 1.4V.
8 FB input Gain-set feedback input; on the MAX9922 the external R1/R2 divider between OUT, FB and REF sets gain = 1 + (R2/R1), and an optional ~1nF noise-reduction capacitor may be connected between OUT and FB.
9 OUT output Voltage output proportional to VSENSE; it swings to within 25mV of the rails but accuracy is maintained only when kept 250mV away from the rails.
10 VDD power_in Power-supply input for +2.85V to +5.5V operation, to be bypassed to GND with a 0.1µF capacitor.
