DAC from ADI with relative accuracy of ±2-LSB INL, 2-ppm/°C 2.5-V reference

Analog Devices, Inc. (ADI) has introduced the AD5689R D/A converter with relative accuracy of ±2-LSB INL, 2-ppm/°C 2.5-V reference. The series provides a straightforward pin compatible 10-bit to 16–bit upgrade/downgrade path for applications in a wide range of markets including communications infrastructure, industrial process control, healthcare and instrumentation.

The AD5689R also includes useful pin functions such as VLOGIC facilitating 1.8-V, 3-V and 5-V logic levels and a GAIN pin enabling the output range to be doubled. The series has both SPI and I2C interface options.

AD5689R 16-bit nanoDAC+ Key Features:
±2 LSB-INL max - suits open loop applications
2-ppm/°C 2.5-V reference – saves board space and removes calibration requirements over temperature
Total Unadjusted Error 2-mV - eliminates need for initial calibration/adjustment
3-mm × 3-mm 16-lead LFCSP and 16-lead TSSOP- for shrinking board/module sizes
4-KV HBM ESD rating - provides system robustness

The AD5689R can be designed into circuits for PLC, I/O cards applications with ADI’s AD5750-2 which is a single-channel, low cost, precision voltage/current output driver amplifier.
