Pin Description
PIN NAME
FUNCTION
1
COM
Common Input. Biased internally at midsupply. Bypass externally to GND with a 0.1µF capacitor. To over-
ride internal biasing, drive with an external supply.
2
IN
Filter Input
3
GND Ground
4
VDD
Positive Supply Input: +5V for MAX7400/MAX7403, +3V for MAX7404/MAX7407
5
OUT Filter Output
6
OS
Offset Adjust Input. To adjust output offset, bias OS externally. Connect OS to COM if no offset adjustment is
needed. Refer to Offset and Common-Mode Input Adjustment section.
7
SHDN Shutdown Input. Drive low to enable shutdown mode; drive high or connect to VDD for normal operation.
8
CLK
Clock Input. To override the internal oscillator, connect to an external clock; otherwise, connect an external
capacitor (COSC) from CLK to GND to set the internal oscillator frequency.
