Pin Description
NAME
FUNCTION
REF
AVDD
External Reference Voltage Input. Sets the analog voltage range. Bypass to AGND with a 4.7FF
capacitor.
Analog +5V Supply Voltage. Bypass to AGND with a 0.1FF capacitor.

DVDD
DOUT
Serial Clock Input. SCLK drives the conversion process and clocks out data at data rates up to
4.8MHz.
Digital Ground
Active-Low Chip-Select Input. Forcing CS high places the MAX11100 shutdown with a typical
current of 0.1FA. A high-to-low transition on CS activates normal operating mode and initiates a
conversion.
Analog Input
Digital Supply Voltage. Bypass to DGND with a 0.1FF capacitor.
Serial Data Output. Data changes state on SCLK’s falling edge. DOUT is high impedance when
CS is high.
