On-chip dynamic power control (DPC) minimizes package power dissipation, which is achieved by regulating the supply voltage (VDPC+) to the VIOUT output driver circuitry from 5 V to 27 V 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. The device uses a versatile 4-wire serial peripheral interface (SPI) that operates at clock rates of up to 50 MHz 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 an integrated 12-bit diagnostic analog-to-digital converter (ADC). Additional robustness is provided by the inclusion of a line protector on the VIOUT, +VSENSE, and −VSENSE pins. When used with its companion power management unit (PMU)/isolator (ADP1031), the AD5758 is capable of enabling customers to develop an eight channel to channel isolated analog output module with less than 2 W power dissipation, while meeting CISPR 11 Class B. PRODUCT HIGHLIGHTS 1. DPC, using an integrated buck dc-to-dc converter for thermal management. When used with the ADP1031, the AD5758 enables eight channel to channel isolated outputs at <2 W dissipated power. 2. Range of advanced diagnostic features, including an integrated ADC for high reliability. 3. Highly robust with output protection from miswire events (±38 V). 4. HART compliant.
