DACxx6x Dual 16-, 14-, 12-Bit, Low-Power, Buffered, Voltage-Output
DACs With 2.5-V, 4-PPM/°C Internal Reference

low-power, voltage-output, dual-channel, 16-, 14-,
– DAC756x (12-Bit): 0.3 LSB INL
and 12-bit digital-to-analog converters (DACs),
– DAC816x (14-Bit): 1 LSB INL
respectively. These devices include a 2.5-V,
4-ppm/°C internal reference, giving a full-scale output

These devices are monotonic, providing excellent

linearity and minimizing undesired code-to-code
transient voltages (glitch). They use a versatile three-
– 4-ppm°C Temperature Drift (Typ)
wire serial interface that operates at clock rates up to
– 10-ppm/°C Temperature Drift (Max)
50 MHz. The interface is compatible with standard

SPI™, QSPI™, Microwire, and digital signal
processor (DSP) interfaces. The DACxx62 devices
