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).
