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 IREF2 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.
