Analog Devices' AD5755, AD5755-1, and AD5757 are quad, voltage and current output DACs that operate with a power supply range from −26.4 V to +33 V. On-chip dynamic power control minimizes package power dissipation in current mode. This is achieved by regulating the voltage on the output driver from 7.4 V to 29.5 V using a DC-to-DC boost converter optimized for minimum on chip power dissipation.
The part uses a versatile 3-wire serial interface that operates at clock rates of up to 30 MHz and is compatible with standard SPI, QSPI™, MICROWIRE™, DSP, and microcontroller inter-face standards. The interface also features optional CRC-8 packet error checking, as well as a watchdog timer that monitors activity on the interface.
