Serial Clock Input. Apply an external serial clock to transfer data to and from the device at data rates
up to 5MHz.
Clock Input. Connect a crystal/resonator between CLKIN and CLKOUT, or drive CLKIN externally with
a CMOS-compatible clock source. Connect CLKIN to GND when using the internal oscillator.
Clock Output. Connect a crystal/resonator between CLKIN and CLKOUT. When enabled, CLKOUT
provides a CMOS-compatible, inverted clock output. CLKOUT can drive one CMOS load. Set CLKDIS
= 0 in the clock register to enable CLKOUT. Set CLKDIS = 1 in the clock register to disable CLKOUT.
Active-Low Chip-Select Input. CS selects the active device in systems with more than one device on
the serial bus. Drive CS low to clock data in on DIN and to clock data out on DOUT. When CS is high,
DOUT is high impedance. Connect CS to GND for 3-wire operation.
Active-Low Reset Input. Drive RESET low to reset the MAX1415/MAX1416 to power-on reset status.

Active-Low Data Ready Output. DRDY goes low when a new conversion result is available in the data
register. When a read operation of a full output word completes, DRDY returns high.
Serial Data Output. DOUT outputs serial data from the data register. DOUT changes on the falling
edge of SCLK and is valid on the rising edge of SCLK. When CS is high, DOUT is high impedance.
Serial Data Input. Data on DIN is clocked in on the rising edge of SCLK when CS is low.
Power Input. Connect V
4.75V to 5.25V power supply for the MAX1416.
