_______________General Description

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.
