Features, Applications

DAC8775 Quad-Channel, 16-Bit Programmable Current Output and Voltage Output Digital-to-Analog Converter with Adaptive Power Management

The is a quad-channel precision, fully integrated, 16-bit, digital-to-analog converter (DAC) with adaptive power management, and is designed to meet the requirements of industrial control applications. The adaptive power management circuit, when enabled, minimizes the power dissipation of the chip. When programmed as a current output, the supply voltage on the current output driver is regulated between 4.5 V and 32 V based on continuous feedback of voltage on the current output pin via an integrated buck/boost converter. When programmed as a voltage output, this circuit generates a programmable supply voltage for the voltage output stage (15 V). DAC8775 also contains an LDO to generate the digital supply (5 V) from a single power supply pin. DAC8775 is also implemented with a Highway Addressable Remote Transducer (HART) Signal Interface to superimpose an external HART signal on the current output. The slew rate of the current output DAC is register programmable. The device can operate with a single external power supply +36 V using the integrated buck/boost converters or with external power supplies when the buck/boost converters are disabled.
