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.
