8-Bit Parallel DAC in QSOP-16 Package

The MAX5480 is a CMOS, 8-bit digital-to-analog converter (DAC) that interfaces directly with most microprocessors. On-chip input latches make the DAC load cycle interface similar to a RAM write cycle, where active-low CS and active-low WR are the only control inputs required.

Linearity of ±1/2 LSB is guaranteed, and power consumption is less than 500 µW. Monotonicity is guaranteed 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.
