_______________________________________________________________________________________
Amplifier Inverting Sense Input (Analog Input)
Analog Output Voltage. High impedance if part is in shutdown.
Reset Value Input (Digital Input).
1: Connect to V
0: Connect to DGND to select 0V as the output reset value.
Power-Down Lockout (Digital Input).
1: Normal operation.
0: Disallows shutdown (device cannot be powered down).
Reset DAC Input (Digital Input). Clears the DAC to its predetermined (RSTVAL) output state. Clearing the
DAC will cause it to exit a software shutdown state.
Active-Low Chip-Select Input (Digital Input)
Serial Data Input. Data is clocked in on the rising edge of SCLK.
Serial Clock Input
Digital Ground
Serial Data Output
User-Programmable Output (Digital Output)
Power-Down Input (Digital Input). Pulling PD high when PDL = V
mum shutdown current of 20µA.
Analog Ground
Buffered Reference Output/Input. In internal reference mode, the reference buffer provides a +2.5V
(MAX5122) or +1.25V (MAX5123) nominal output, externally adjustable at REFADJ. In external reference
mode, disable the internal reference by pulling REFADJ to V
Analog Reference Adjust Input. Bypass with a 33nF capacitor to AGND. Connect to V
external reference.
Positive Power Supply. Bypass with a 0.1µF capacitor in parallel with a 4.7µF capacitor to AGND.
