Product Details
The AD5753 is a single-channel, voltage and current output digital-to-analog converter (DAC) that operates with a power supply range from a minimum of −33 V on AVSS to a maximum of +33 V on AVDD1 with a maximum operating voltage of 60 V between the two rails. On-chip dynamic power control (DPC) minimizes package power dissipation. This minimization is achieved by using buck dc-to-dc converters optimized for minimum on-chip power dissipation to regulate the voltage (VDPC+ and VDPC−) that is sent to the VIOUT output driver circuitry from the ±5 V to ±27 V supply voltage. The CHART pin enables a Highway Addressable Remote Transducer® (HART) signal to be coupled on the current output.
The AD5753 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™, digital signal processor (DSP), and microcontroller interface standards. The interface features an optional SPI cyclic redundancy check (CRC) and a watchdog timer (WDT). The AD5753 offers improved diagnostic features from earlier versions of similar DACs, such as output current monitoring and an integrated, 12-bit diagnostic analog-to-digital converter (ADC). The inclusion of a line protector on the VIOUT, +VSENSE, and −VSENSE pins provides additional robustness.
Product Highlights
- Range of advanced diagnostic features, including integrated ADC with two external input pins.
- DPC, using integrated buck dc-to-dc converters for thermal management, which enables higher channel count in small size module housing.
- Programmable power control (PPC) mode to enable faster than DPC settling time (15 μs typical).
- Highly robust with output protection from miswire events (±38 V).
- HART compliant.
Applications
- Process control
- Actuator control
- Channel isolated analog outputs
- Programmable logic controller (PLC) and distributed control systems (DCS) applications
- HART network connectivity

Precision DAC Error Budget Tool
The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.
