CAPACITANCE
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.
Filter Input
Ground
Positive Supply Input: +5V for MAX7400/MAX7403, +3V for MAX7404/MAX7407
Filter Output
Offset Adjust Input. To adjust output offset, bias OS externally. Connect OS to COM if no offset adjustment is
needed. Refer to
Shutdown Input. Drive low to enable shutdown mode; drive high or connect to V
Clock Input. To override the internal oscillator, connect to an external clock; otherwise, connect an external
capacitor (C
