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 g5V supplies. No reference current (IREF) trimming is required for

most applications since the full scale output current is typically g1 LSB of 255 IREF/ 256. Relative accuracies of better than g0.19 assure 8-bit monotonicity and linearity

while zero level output current of less than 4 mA provides

8-bit zero accuracy for IREFt2 mA. The power supply currents of the DAC0808 series are independent of bit codes,

and exhibits essentially 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.
