Low-power voltage-output dual-channel digital-to-analog converters

This post is sponsored by Texas Instruments. The Texas Instruments (TI) DAC856xT, DAC816xT, and DAC756xT are low-power, voltage-output, dual-channel, 16-, 14-, and 12-bit digital-to-analog converters (DACs), respectively. The devices include a 2.5V, 4-ppm/C internal reference, giving a full-scale output voltage range of 2.5V or 5V. The internal reference has an initial accuracy of ±5mV and can source or sink up to 20mA at the VREFIN/VREFOUT pin. The devices are monotonic, providing high linearity and minimizing undesired code-to-code transient voltages (glitch). They use a versatile three-wire serial interface that operates at clock rates up to 50MHz. The interface is compatible with standard SPI, QSPI, Microwire, and digital signal processor (DSP) interfaces, says the company.
