SBAS871A – AUGUST 2017 – REVISED DECEMBER 2017 DACx0504 Quad, 16-, 14-Bit, SPI Voltage Output DACs With Internal Reference
1 Features 3 Description The DACx0504 is a pin-compatible family of lowpower, four-channel, buffered voltage-output, digitalto-analog converter (DAC) with 16-and 14-bit
resolution. The DACx0504 includes a 2.5-V, 5ppm/В°C internal reference, eliminating the need for an
external precision reference in most applications. A
user-selectable gain configuration provides full-scale
output voltages of 1.25 V (gain = ВЅ), 2.5 V (gain = 1),
or 5 V (gain = 2). This device operates from a single
2.7-V to 5.5-V supply, is specified monotonic, and
provides high linearity of В±1 LSB INL. 1 Performance
– INL: ±1 LSB Maximum at 16-Bit Resolution
– TUE: ±0.14% of FSR Maximum
Integrated 2.5 V Precision Internal Reference
– Initial Accuracy: ±5 mV, Maximum
– Low Drift: 5 ppm/°C, Typical
High Drive Capability: 20 mA With 0.5 V From
Supply Rails
Flexible Output Configuration …
