Data Sheet Industrial Current Out Driver, Single-Supply, 55 V Maximum Supply, Programmable Ranges AD5749 08923-001 FEATURES Current output ranges: 0 mA to 24 mA or 4 mA to 20 mA ±0.03% FSR typical total unadjusted error (TUE) ±5 ppm/°C typical output drift 2% overrange Flexible serial digital interface On-chip output fault detection PEC error checking Asynchronous CLEAR function Power supply range AVDD: 12 V (± 10%) to 55 V (maximum) Output loop compliance to AVDD − 2.75 V Temperature range: −40°C to +105°C 32-lead, 5 mm × 5 mm LFCSP package APPLICATIONS Process control Actuator control PLCs GENERAL DESCRIPTION The AD5749 is a single channel, low cost, precision, current output driver with hardware or software programmable output ranges. The software ranges are configured via an SPI-/MICROWIRE™compatible serial interface. The AD5749 targets applications in PLC and industrial process control. The analog input to the AD5749 is provided from a low voltage, single-supply digital-toanalog converter (DAC) and is internally conditioned to provide the desired output current/voltage range. The output current range is programmable across two current ranges: 0 mA to 24 mA, or 4 mA to 20 mA. Current output is open-circuit protected and can drive inductive loads of 0.1 H. The device is specified to operate with a power supply range from 10.8 V to 55 V. Output loop compliance is 0 V to AVDD − 2.75 V. The flexible serial interface is SPI and MICROWIRE compatible and can be operated in 3-...
