Description
Max5480 8-bit Parallel Dac In Qsop-16 Package
Manufacturer
Maxim Integrated Products, Inc.
Datasheet
The MAX5480 is a CMOS, 8-bit digital-to-analog con-
verter (DAC) that interfaces directly with most micro-
processors. On-chip input latches make the DAC load
cycle interface similar to a RAM write cycle, where CS
and WR are the only control inputs required.
Linearity of ±1/2LSB is guaranteed, and power con-
sumption is less than 500µW. Monotonicity is guaran-
teed over the full operating temperature range.
The MAX5480 can be operated in either voltage-output
or current-output mode. It is available in a small 16-pin
QSOP package.
