DAC80508-04 Evaluation Module
Description
The
DAC80508-04EVM
is an easy-to-use platform
to evaluate the functionality and performance of the
DACx0508
and
DACx0504
DAC80508-04EVM has optional circuits and jumpers
to configure the device for different applications. The
DAC80508 is installed on the EVM. The user can
replace the DAC80508 with the DAC80504.
The DAC80508 and DAC80504 are 16-bit buffered
voltage-output digital-to-analog converters (DAC).
The DAC80508 has 8 DACs, and the DAC80504
has 4 DACs. The devices includes a 2.5-V, 5-
ppm/°C internal reference and a user-selectable gain
configuration giving full-scale output voltages of 1.25
V, 2.5 V, or 5 V. The devices operate from a single
2.7-V to 5.5-V supply, is verified monotonic, and
provides exceptional linearity of ±1 LSB INL.
