Analog Devices Inc. AD5758 Digital-to-Analog Converter (DAC)

Analog Devices AD5758 Digital-to-Analog Converter (DAC) is a single-channel, voltage and current output digital-to-analog converter (DAC). This DAC operates with a power supply range from -33V (minimum) on AVSS to +33V (maximum) on AVDD1 with a maximum operating voltage between the two rails of 60V. On-chip dynamic power control (DPC) minimizes package power dissipation. This is achieved by regulating the supply voltage (VDPC+) to the VIOUT output driver circuitry from 5V to 27V using a buck DC-to-DC converter, optimized for minimum on-chip power dissipation. The CHART pin enables a HART® signal to be coupled onto the current output.

Analog Devices AD5758 uses a versatile 4-wire serial peripheral interface (SPI) that operates at clock rates of up to 50MHz and is compatible with standard SPI, QSPI™, MICROWIRE™, DSP, and microcontroller interface standards. The interface also features an optional SPI cyclic redundancy check (CRC) and a watchdog timer (WDT). The AD5758 offers improved diagnostic features from its predecessors, such as output current monitoring and an integrated 12-bit diagnostic analog-to-digital converter (ADC). Additional robustness is provided by the inclusion of a fault protection switch on the VIOUT, +VSENSE, and -VSENSE pins.
