XOUT, XIN - A gate inside the chip is connected to these pins and can be used with a
crystal to provide the system clock for the device. Alternatively, an external (CMOS
compatible) clock can be supplied into XIN pin to provide the system clock for the device.
CPU Clock Output
2
CPUCLK - Output of on-chip oscillator which can drive one standard CMOS load.
Control Pins and Serial Data I/O
Serial Clock Input
5
SCLK - A clock signal on this pin determines the input and output rate of the data for the
SDI and SDO pins respectively. The SCLK pin will recognize clocks only when CS is low.
Serial Data Output
6
SDO -The serial data port output pin. Its output is in a high impedance state when CS is
high.
Chip Select
7
CS - When low, the port will recognize SCLK. An active high on this pin forces the SDO
pin to a high impedance state. CS should be changed when SCLK is low.
Reset
19
RESET - When reset is taken low, all internal registers are set to their default states.
Interrupt
20
INT - When INT goes low it signals that an enabled event has occurred.
Serial Data Input
23
SDI - The serial data port input pin. Data will be input at a rate determined by SCLK.
Measurement and Reference Input
Differential
Analog Inputs
9,10,15,16
AIN1+, AIN1-, AIN2+, AIN2- - Differential analog input pins.
Voltage
Reference Output
11
VREFOUT - The on-chip voltage reference output. The voltage reference has a nominal
magnitude of 2.5 V and is referenced to the AGND pin on the converter.
Voltage
Reference Input
12
VREFIN - The input establishes the voltage reference for the on-chip modulator.
Power Supply Connections
Positive
Digital Supply
3
VD+ - The positive digital supply relative to DGND.
Digital Ground
4,9,10
DGND - The common-mode potential of digital ground must be equal to or above the
common-mode potential of AGND.
Positive
Analog Supply
14
VA+ - The positive analog supply relative to AGND.
Analog Ground
13
AGND - The analog ground pin must be at the lowest potential.
Test Output
8,17,18,21,22 TSTO - These pins are used for factory testing and must be left floating.
