Texas Instruments DAC8775 Quad-Channel 16-Bit DAC
Texas Instruments DAC8775 Quad-Channel 16-Bit Digital-to-Analog Converter (DAC) comes with adaptive power management. This DAC 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 4.5V and 32V. This regulation is based on the continuous feedback of voltage on the current output pin via an integrated buck/boost converter. This circuit generates a programmable supply voltage for the voltage output stage (±15V) when programmed as voltage output. The Texas Instruments DAC8775 also contains an LDO to generate a single power supply pin's digital supply (5V).
