AD5737

Data Sheet Quad-Channel, 12-Bit, Serial Input, 4 mA to 20 mA Output DAC with Dynamic Power Control and HART Connectivity AD5737 FEATURES 12-bit resolution and monotonicity Dynamic power control for thermal management or external PMOS mode Current output ranges: 0 mA to 20 mA, 4 mA to 20 mA, and 0 mA to 24 mA ±0.1% total unadjusted error (TUE) maximum User-programmable offset and gain On-chip diagnostics On-chip reference: ±10 ppm/°C maximum −40°C to +105°C temperature range APPLICATIONS Process control Actuator control PLCs HART network connectivity GENERAL DESCRIPTION The AD5737 is a quad-channel current output DAC that operates with a power supply range from 10.8 V to 33 V. On-chip dynamic power control minimizes package power dissipation by regulating the voltage on the output driver from 7.4 V to 29.5 V using a dc-to-dc boost converter optimized for minimum on-chip power dissipation. Each channel has a corresponding CHART pin so that HART signals can be coupled onto the c...
