16-bit quad SPI DAC achieves ±4-LSB INL

16-bit quad SPI DAC achieves ±4-LSB INL

The LTC2654 quad-voltage output 16- and 12-bit D/A converter with internal reference achieves 16-bit performance of ±4-LSB INL max over temperature. The part’s integrated reference achieves 2 -pm/°C typ and 10-ppm/°C max temperature coefficient. In addition, offset error is ±2 mV max and gain error is 0.1% max.

The part offers 8.9-µs settling time for a half-scale step and 3-nV•s crosstalk. Offered in 20-pin 4 x 4-mm QFN and 16-pin TSSOP packages, the DAC operates from a single 2.7 to 5.5-V supply and communicates via a four-wire SPI/Microwire-compatible interface up to 50 MHz. (Ea/1,000: 12-bit options, from $4.80; 16-bit options, $11.70 — available now.)
