16-bit D/A converter targets wide application range

Analog Devices Inc. has introduced the AD5689R D/A converter. This 16-bit dual nanoDAC+ continues the series of ADI’s nanoDAC products offering high performance in smaller packages.

With relative accuracy of ±2-LSB INL, 2-ppm/°C 2.5-V reference, and space saving packages, this combination allows analog designers to address a wider range of applications without having to trade off performance for footprint. 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.

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.
