Figure 3. Gauge Response
To drive the gauge’s pointer to a particular angle, the
microcontroller sends a 10–bit digital word into the serial
port. These 10 bits are divided as shown in Figure 4.

The 10 bits are shifted into the device’s shift register MSB
first using an SPI compatible scheme. This method is shown
in Figure 5. The CS must be high and remain high for SCLK
to be enabled. Data on SI is shifted in on the rising edge of
the synchronous clock signal. Data in the shift register
changes at SO on the falling edge of SCLK. This
arrangement allows the cascading of devices. SO is always
enabled. Data shifts through without affecting the outputs
until CS is brought low. At this time the internal DAC is
updated and the outputs change accordingly.

Figure 6 shows the power–up sequence for the CS4192.
Note the IC requires a pulse on the Chip Select (CS) pin to
clear the Status Fault (ST) after power up. OE must be high
before the falling edge of CS to enable the output buffers.
