DAC0808

8-Bit D/A Converter

General Description

The DAC0808 is an 8-bit monolithic digital-to-analog con-

verter (DAC) featuring a full scale output current settling time

of 150 ns while dissipating only 33 mW with

No reference current (I

applications since the full scale output current is typically

LSB of 255 I

level output current of less than 4 µA provides 8-bit zero

accuracy for I

DAC0808 is independent of bit codes, and exhibits essen-

tially constant device characteristics over the entire supply

voltage range.

The DAC0808 will interface directly with popular TTL, DTL or

CMOS logic levels, and is a direct replacement for the

MC1508/MC1408. For higher speed applications, see

DAC0800 data sheet.
