Description

SCLK

Serial Clock. SCLK provides the serial clock for accessing data from the part and writing serial data

to the control registers.

DOUT

Data Out. The data on this pin represents data being read from the control registers and is clocked

out on the falling edge of the SCLK.

DIN

Data In. Data written to the control registers is provided on this input and is clocked in on the

rising edge of the SCLK.

Chip Select, Active Low. This input frames the serial data transfer.

AUX COM

Auxiliary Grounds. Connect to GND for proper operation.

RST

Reset, Active Low. This input resets the embedded microcontroller to a known state.

AUX DAC

Auxiliary DAC Analog Voltage Output.

VDD

+3.3 V Power Supply.

AUX ADC

Auxiliary ADC Analog Input Voltage.

VREF

Precision Reference Output.

COM

Common. Reference point for all circuitry in the ADIS16201.

S = Supply; O = Output; I = Input.
