Positive Supply Voltage
Sampling Analog Input, 0 to V
Active-Low Shutdown Input. Pulling SHDN low shuts down the device and reduces the supply current
to 2µA (typ).
Reference Voltage for Analog-to-Digital Conversion. Internal 2.5V reference output. Bypass with a
4.7µF capacitor.
Analog and Digital Ground
Serial-Data Output. DOUT changes state at SCLK’s rising edge. High impedance when CS is high.
Active-Low Chip Select. Initiates conversions on the falling edge. When CS is high, DOUT is high
impedance.
Serial-Clock Input. SCLK drives the conversion process and clocks data out at rates up to 6.4MHz
(MAX1084) or 4.8MHz (MAX1085).
