AD5753

Data Sheet Single-Channel, 16-Bit Current and Voltage DAC with Dynamic Power Control and HART Connectivity AD5753 FEATURES 16-bit resolution and monotonicity Positive and negative DPC for thermal management Current or voltage output available on a single terminal Current output ranges: 0 mA to 20 mA, 4 mA to 20 mA, 0 mA to 24 mA, ±20 mA, ±24 mA, and −1 mA to +22 mA Voltage output ranges (with 20% overrange): 0 V to 5 V, 0 V to 10 V, ±5 V, and ±10 V User programmable offset and gain Advanced on-chip diagnostics, including a 12-bit ADC 2 external ADC input pins On-chip reference Robust architecture, including output fault protection −40°C to +115°C temperature range 40-lead, 6 mm × 6 mm LFCSP package APPLICATIONS Process control Actuator control Channel isolated analog outputs Programmable logic controller (PLC) and distributed control systems (DCS) applications HART network connectivity GENERAL DESCRIPTION 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.
