DAC0808/DAC0807/DAC0806 8-Bit D/A Converters

General Description

The DAC0808 series is an 8-bit monolithic digital-to-analog
converter (DAC) featuring a full scale output current settling
time of 150 ns while dissipating only 33 mW with
plies. No reference current (I

rents of the DAC0808 series are independent of bit codes,
and exhibits essentially constant device characteristics over

the device beyond its specified operating conditions.

Note 2: Range control is not required.
