The RS1324 device is a full-featured, generalpurpose, quad, 12bit, voltage-output, digital-to-analog converter(DAC) that can operate from a single 2.7V to 5.5V supply and consumes 2.5mW at 3V or 6mW at 5V. The RS1324 is packaged in MSOP10 package. The on-chip output amplifier allows rail-to-rail output swing and the three-wire serial interface operates at clock rates up to 40MHz over the entire supply voltage range. Competitive devices are limited to 25MHz clock rates at supply voltages in the 2.7V to 3.6V range. The serial interface is compatible with standard SPI, QSPI, MICROWIRE, and DSP interfaces. The reference for the RS1324 serves all four channels and can vary in voltage between 1V and VA, providing the widest possible output dynamic range. The RS1324 has a 16-bit input shift register that controls the outputs to be updated, the mode of operation, the power-down condition, and the binary input data. All four outputs can be updated simultaneously or individually depending on the setting of the two mode of operation bits.
