Description

The AD5755 is a quad, voltage and current output DAC that operates 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.Product HighlightsDynamic power control for thermal management.16-bit performance.Multichannel.ApplicationsProcess controlActuator controlPLCs
