The 8-bit DAC5311, 10-bit DAC6311, and 12-bit DAC7311 devices (DACx311) are low-power, single-channel, voltage output DACs. These devices are monotonic by design, provide excellent linearity, and minimize undesired code-to-code transient voltages while offering an easy upgrade path within a pin-compatible family. All devices use a versatile, three-wire serial interface that operates at clock rates of up to 50 MHz and is compatible with standard SPI, QSPI, Microwire, and digital signal processor (DSP) interfaces.
