Single-Channel, 16-Bit Current and Voltage DAC with Dynamic Power Control and HART Connectivity Data Sheet AD5753 FEATURES GENERAL DESCRIPTION 16-bit resolution and monotonicity The AD5753 is a single-channel, voltage and current output Positive and negative DPC for thermal management digital-to-analog converter (DAC) that operates with a power Current or voltage output available on a single terminal supply range from a minimum of 33 V on AV to a maximum of SS Current output ranges: 0 mA to 20 mA, 4 mA to 20 mA, +33 V on AVDD1 with a maximum operating voltage of 60 V 0 mA to 24 mA, 20 mA, 24 mA, and 1 mA to +22 mA between the two rails. On-chip dynamic power control (DPC) Voltage output ranges (with 20% overrange): 0 V to 5 V, minimizes package power dissipation. This minimization is 0 V to 10 V, 5 V, and 10 V achieved by using buck dc-to-dc converters optimized for User programmable offset and gain minimum on-chip power dissipation to regulate the voltage Advanced on-chip diagnostics, including a 12-bit ADC (V and V ) that is sent to the VI output driver circuitry DPC+ DPC OUT 2 external ADC input pins from the 5 V to 27 V supply voltage. The C pin enables a HART On-chip reference Highway Addressable Remote Transducer (HART) signal to be Robust architecture, including output fault protection coupled on the current output. 40C to +115C temperature range The AD5753 uses a versatile, 4-wire, serial peripheral interface 40-lead, 6 mm 6 mm LFCSP package (SPI) that operates at clock rates of up to 50 MHz and is APPLICATIONS compatible with standard SPI, QSPI, MICROWIRE, digital Process control signal processor (DSP), and microcontroller interface standards. Actuator control The interface features an optional SPI cyclic redundancy check Channel isolated analog outputs (CRC) and a watchdog timer (WDT). The AD5753 offers Programmable logic controller (PLC) and distributed control improved diagnostic features from earlier versions of similar systems (DCS) applications DACs, such as output current monitoring and an integrated, 12-bit HART network connectivity diagnostic analog-to-digital converter (ADC). The inclusion of a line protector on the VIOUT, +VSENSE, and VSENSE pins provides additional robustness. PRODUCT HIGHLIGHTS 1. Range of advanced diagnostic features, including integrated ADC with two external input pins. 2. DPC, using integrated buck dc-to-dc converters for thermal management, which enables higher channel count in small size module housing. 3. Programmable power control (PPC) mode to enable faster than DPC settling time (15 s typical). 4. Highly robust with output protection from miswire events (38 V). 5. HART compliant.
