SLASEM5A – JULY 2017 – REVISED JANUARY 2018 DACx0508 Octal, 16-, 14-, 12-Bit, SPI, Voltage Output DAC with Internal Reference
1 Features 3 Description The DACx0508 is a pin-compatible family of low
power, eight-channel, buffered voltage-output, digitalto-analog converters (DACs) with 16-, 14-and 12-bit
resolution. The DACx0508 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). The 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
