__________________General DescriptionThe +5V MAX5250 combines four low-power, voltage-output, 10-bit digital-to-analog converters (DACs) andfour preci

MAX5250Figure 5 shows the serial-interface timing requirements.The chip-select pin (CS) must be low to enable theDAC’s serial interface. When CS is hi

Power-Down (PDL)The power-down lockout pin PDL disables softwareshutdown when low. When in shutdown, transitioningPDL from high to low wakes up the pa

__________Applications InformationUnipolar OutputFor a unipolar output, the output voltages and the refer-ence inputs have the same polarity. Figure 9

MAX5250Using an AC Reference In applications where the reference has AC signal com-ponents, the MAX5250 has multiplying capability withinthe reference

Power-Supply Considerations On power-up, all input and DAC registers are cleared(set to zero code) and DOUT is in Mode 0 (serial datais shifted out of
