General Description
The DAC0808 series 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 g5V sup-
plies No reference current (IREF) trimming is required for
most applications since the full scale output current is typi-
cally g1 LSB of 255 IREF 256 Relative accuracies of bet-
ter than g0 19% assure 8-bit monotonicity and linearity
while zero level output current of less than 4 mA provides
8-bit zero accuracy for IREFt2 mA The power supply cur-
rents of the DAC0808 series are 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
