DAC0808 DAC0807 DAC0806 8-Bit D A Converters
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

Note 1 Absolute Maximum Ratings indicate limits beyond which damage to the device may occur DC and AC electrical specifications do not apply when operating
the device beyond its specified operating conditions
Note 2 Range control is not required
Note 3 The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX iJA and the ambient temperature TA The maximum
allowable power dissipation at any temperature is PD e (TJMAX b TA) iJA or the number given in the Absolute Maixmum Ratings whichever is lower For this
device TJMAX e 125 C and the typical junction-to-ambient thermal resistance of the dual-in-line J package when the board mounted is 100 C W For the dual-in-
line N package this number increases to 175 C W and for the small outline M package this number is 100 C W
Note 4 Human body model 100 pF discharged through a 1 5 kX resistor
Note 5 All current switches are tested to guarantee at least 50% of rated current
Note 6 All bits switched
Note 7 Pin-out numbers for the DAL080X represent the dual-in-line package The small outline package pinout differs from the dual-in-line package
