The DAC8830 and DAC8831IRGYR 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 (1 LSB INL), low glitch, low noise, and fast settling (1.0 µS to 1/2 LSB of full-scale output) over the specified temperature range of -40°C to +85°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 a DSP or microprocessor.
The DAC8830 output is 0 V to VREF. However, the DAC8831IRGYR provides bipolar output (±VREF) when working with an external buffer. The DAC8830 and DAC8831IRGYR 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 DAC8831IRGYR in an SO-14 package. Both have industry standard pinouts. The DAC8831IRGYR is also available in a QFN-14 package.
