The DAC8830 and DAC8831 are single, 16-bit, serial-input, voltage-output digital-to-analog converters (DACs) operating from a single 3-V to 5-V power supply. These converters provide excellent linearity, low glitch, low noise, and fast settling over the specified temperature range of -55°C to 125°C. The output is unbuffered, which reduces the power consumption and the error introduced by the buffer. These parts feature a standard high-speed (clock up to 50 MHz), 3-V or 5-V SPI serial interface to communicate with the DSP or microprocessors. The DAC8830 output is 0 V to VREF. However, the DAC8831 provides bipolar mode output (±VREF) when working with an external buffer. The DAC8830 and DAC8831 are both reset to zero-code after power up. For optimum performance, a set of Kelvin connections to external reference and analog ground input are provided on the DAC8831. The DAC8830 is available in an SO-8 package and the DAC8831 is available in an SO-14 package. Both have industry standard pinouts.
