The AD5758 is a single-channel, voltage and current output digital-to-analog converter (DAC) that operates with a power supply range from −33 V (minimum) on AVSS to +33 V (maximum) on AVDD1 with a maximum operating voltage between the two rails of 60 V. 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.
- 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.
- Range of advanced diagnostic features, including an integrated ADC for high reliability.
- Highly robust with output protection from miswire events (±38 V).
- HART compliant.
- Process control
- Actuator control
- Channel isolated analog outputs
- Programmable logic controller (PLC) and distributed control systems (DCS) applications
- HART network connectivity

Evaluation Kits (2)
The DEMO-AD5758-AO8Z Board demonstrates a system-level concept where the AD5758 and the ADP1031 are used together to implement a compact, eight channel, channel-to-channel isolated, analog output (AO) module. The module is designed to dissipate less than 2 W worst case power dissipation over a wide range of operating conditions.
This user guide describes the evaluation board for the AD5758, a single-channel, voltage and current output, digital-to-analog converter (DAC) with on-chip dynamic power control (DPC) to minimize package power dissipation.
For full details, refer to the AD5758 data sheet. Consult the data sheet when using the EVAL-AD5758SDZ. The configuration of the various link options is explained in the Evaluation Board Hardware section. The installation of the companion software is discussed in the Evaluation Software Quick Start Procedures section.
The EVAL-AD5758SDZ, as shown in Figure 1, requires the EVAL-SDP-CS1Z board. The EVAL-AD5758SDZ interfaces to the USB port of the PC via the EVAL-SDP-CS1Z board. The Analysis|Control|Evaluation (ACE) software allows simplified programming of the AD5758, and is available with the EVAL-AD5758SDZ evaluation board.
