DAC0808LCMX/NOPB Data Converter IC Digital to Analog Converters - DAC 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 ±5V supplies. No reference current (IREF) trimming is required for most applications since the full scale output current is typically ±1 LSB of 255 IREF/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 IREF≥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.

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.
