Reset Value Input
1: Connect to V
0: Connect to DGND to select zero as the reset value.
Load DACs A and B
Clear Input. Both DAC outputs go to zero or midscale. Clears both DAC internal registers (input
register and DAC register) to its predetermined (RSTV) state.
Chip-Select Input
Serial Data Input. Data is clocked in on the rising edge of SCLK.
Serial Clock Input
Digital Ground
Serial Data Output
Power-Down Lockout. Disables shutdown of both DACs when low.
Reference Output. Reference provides a 2.465V (MAX5231) or 1.234V (MAX5230) nominal output.
