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 (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 the DSP or microprocessors.
The DAC8830 output is 0 V to V
REF
. However, the
DAC8831 provides bipolar output (±V
REF
) 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 (see
Table 3,
the
cross-reference table in the
Application Information
section for details). The DAC8831 is also available in
a QFN-14 package.
