On Chip Diagnostics
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.
