DESCRIPTION

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 (see Table 3, the

Cross Reference table in the Application Information

section for details).
