DAC7311IDCKR

The DAC7311IDCKR is an 1-channel 12-bit low-power voltage output Digital-to-analog Converter (DAC) with the low power consumption of these devices in normal operation makes it ideally suited for portable, battery-operated applications. This device is 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. The device uses a versatile, 3-wire serial interface that operates at clock rates of up to 50MHz and is compatible with standard SPI™, QSPI™, MICROWIRE and digital signal processor (DSP) interfaces. The device incorporates a power-on reset (POR) circuit that ensures the DAC output powers up at 0V and remains there until a valid write to the device occurs. The DAC7311 contains a power-down feature, accessed over the serial interface that reduces current consumption of the device to 0.1µA at 2V in power-down mode.
