ADI introduces smaller packaged quad 12/14/16 bit DAC with improved DC performance

Analog Devices, Inc. has introduced a series of quad 16-, 14- and 12-bit digital to analog converters in 16-lead surface mount LFCSP or leaded TSSOP packages. ADI's new AD568xR nanoDAC+ series of quad D/A converters provide better DC performance (INL, offset error and gain error) and are available in smaller package size. These converters are available with a choice of on-chip or external reference and SPI or I²C control interface.

The AD568xR series DACs are suitable for applications such as PLC I/O cards, digital oscilloscopes, signal generators and optical modules.

"Customers, who previously had to trade off board area to achieve higher levels of digital-to-analog accuracy and reference drift performance now have a solution that meets all of their requirements," said Donal Geraghty, director of precision D/A converters, Analog Devices. "The AD5686R delivers four D/A converters with 16-bit accuracy and a 2-ppm/°C reference in a tiny 3mm x 3mm package."

Features:
1. Relative accuracy: ±2LSB max at 16-bits
2. On-chip 2.5-V, 2-ppm/°C integrated reference and low drift
3. 3 x 3 mm, chip scale 16-pin LFCSP package
4. 4-kV HBM ESD rating
5. 16, 14 or 12 bits resolution
6. SPI or I²C interfaces
7. Available in high and mid range performance grades (B and A)

Samples and evaluation board are currently available.
