Description

The DAC7568, DAC8168, and DAC8568 are low-power, voltage-output, eight-channel, 12-, 14-, and 16-bit digital-to-analog converters (DACs), respectively. These devices include a 2.5V, 2ppm/°C internal reference (disabled by default), giving a full-scale output voltage range of 2.5V or 5V. The internal reference has an initial accuracy of 0.004% and can source up to 20mA at the VREFIN/VREFOUT pin. These devices are monotonic, providing excellent linearity and minimizing undesired code-to-code transient voltages (glitch). They use a versatile 3-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.
