DAC0808

8-Bit D/A Converter

General Description

Features

n Relative accuracy: 0.19% error maximum

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

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

n Full scale current match: 1 LSB typ

of 150 ns while dissipating only 33 mW with 5V supplies.

n Fast settling time: 150 ns typ

n Noninverting digital inputs are TTL and CMOS

compatible

n High speed multiplying input slew rate: 8 mA/µs

n Power supply voltage range: 4.5V to 18V

No reference current (I_REF) trimming is required for most

applications since the full scale output current is typically

LSB of 255 I_REF/256. Relative accuracies of better than

0.19% assure 8-bit monotonicity and linearity while zero

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

accuracy for I_REF≥2 mA. The power supply currents of the

DAC0808 is independent of bit codes, and exhibits essen-

tially constant device characteristics over the entire supply

voltage range.

@ ±

n Low power consumption: 33 mW

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.
