8-Bit D/A Converter
The DAC0808 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 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 ?A provides 8-bit zero accuracy for IREF>=2 mA. The power supply currents of the DAC0808 is 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.
