Serial Data Input of the 16-bit shift register. Data is clocked into the register on the rising edge of SCLK.
Chip Select (active low). Enables data to be shifted into the 16-bit shift register. Programming commands
are executed at the rising edge of
Serial Clock Input. Data is clocked in on the rising edge of SCLK.
Asynchronous reset input (active low). Clears all registers to their default state (FFhex for DAC A and
DAC B registers); all other registers are reset to 0 (including the input shift register).
Positive Power Supply (2.7V to 5.5V). Bypass with 0.22µF to GND.
Ground
Negative Power Supply 0V or (-1.5V to -5.5V). Tie to GND for single supply operation. If a negative supply
is applied, bypass with 0.22µF to GND.
DAC A Output Voltage (Buffered). Resets to full scale. Connect 0.1µF capacitor or greater to GND.
DAC B Output Voltage (Buffered). Resets to full scale. Connect 0.01µF capacitor or greater to GND.
DAC C Output Voltage (Unbuffered). Resets to zero.
