DAC0808
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
No reference current (I
) trimming is required for most
REF
applications since the full scale output current is typically
LSB of 255 I
/256. Relative accuracies of better than
REF
±
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
2 mA. The power supply currents of the
REF
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.
