Analog Devices has introduced the AD5755 data converter which incorporates four 16-bit DACs with programmable voltage or 4–20-mA output drivers.

There is a dynamic power control which works by continually sensing the load impedance and delivering the required power to the load.

The DAC has a specified total unadjusted error of 0.05 % and a relative accuracy of ±0.003% max.

The device, which supports standard industrial voltage and current output ranges, can be used with standard HART (Highway Addressable Remote Transducer) protocol modems.

Also integrated on-chip is a 5ppm/°C internal reference, user-accessible offset and gain registers and a 30MHz SPI (serial peripheral interface) compatible interface.

The device is specified over the extended industrial temperature range of –40°C to +105°C and is housed in 9x9mm LFCSP (lead-frame chip scale package).
