3. PIN DESCRIPTIONS
Clock Generator
OSC1; OSC2 – Master Clock
An inverting amplifier inside the chip is connected between these pins and can be used with a
crystal to provide the master clock for the device. Alternatively, an external (CMOS compatible)
clock (powered relative to VD+) can be supplied into the OSC2 pin to provide the master clock
for the device.
Control Pins and Serial Data I/O
CS – Chip Select
When active low, the port will recognize SCLK. When high the SDO pin will output a high
impedance state. CS should be changed when SCLK = 0.
SDI – Serial Data Input
SDI is the input pin of the serial input port. Data will be input at a rate determined by SCLK.
SDO – Serial Data Output
SDO is the serial data output. It will output a high impedance state if CS = 1.
SCLK – Serial Clock Input
A clock signal on this pin determines the input/output rate of the data for the SDI/SDO pins
respectively. This input is a Schmitt trigger to allow for slow rise time signals. The SCLK pin
will recognize clocks only when CS is low.
A0 – Logic Output (Analog), A1 – Logic Output (Analog)
The logic states of A1-A0 mimic the A1-A0 bits in the Configuration Register. Logic
Output 0 = VA-, and Logic Output 1 = VA+.
