GENERAL DESCRIPTION

The AD5755/AD5735 is a quad, voltage and current output DAC, which operates with a power supply range from -26v to +33v. On chip dynamic power control minimizes package power dissipation in current mode. This is achieved by regulating the voltage on the output driver from between 7V-30V.

The part uses a versatile 3-wire serial interface that operates at clock rates up to 30 MHz and that is compatible with standard SPI?, QSPI?, MICROWIRE?, DSP and microcontroller interface standards. The interface also features optional CRC-8 packet error checking as well as a watchdog timer that monitors activity on the interface.
