●The DAC5311 is an 8-bit, low-power, single-channel, voltage output, digital-to-analog converters (DAC). It is monotonic by design and provides excellent linearity and minimizes 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 50 MHz and is compatible with standard SPI, QSPI, MICROWIRE, and digital signal processor (DSP) interfaces.
●DAC5311 uses an external power supply as a reference voltage to set the output range. The devices incorporate a power-on reset (POR) circuit that ensures the DAC output powers up at 0 V and remains there until a valid write to the device occurs. It contains a power-down feature, accessed over the serial interface, that reduces current consumption of the device to 0.1 µA at 1.8 V in power-down mode. The low power consumption of this part in normal operation makes it ideally suited for portable battery-operated equipment. The power consumption is 0.55 mW at 5 V, reducing to 2.5 µW in power-down mode.
●DAC5311 is pin-compatible with the DAC8311 and DAC8411, offering an easy upgrade path from 8-bit resolution to 14- and 16-bit resolution. The device is available in a small 6-pin SC70 package. This package offers a flexible solution over the automotive temperature range of
●40°C to 85°C.
