DAC 1-CH Segment 16-bit 8-Pin SOIC T/R

The DAC8830 and DAC8831are 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 Vor 5 V SPI serial interface to communicatewith a DSP or microprocessor. The DAC8830 output is0 V to VREF. However, the DAC8831 provides bipolar 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 in an SO-14 package.Both have industry standard pinouts. The DAC8831 is also available in a QFN-14 package.
