DAC0808/DAC0807/DAC0806 8-Bit D/A ConvertersGeneral Des criptionThe DAC0808 series is an 8-bit monolithic digital-to-analogconverter (DAC) featuring a full scale output current settlingtime of 150 ns while dissipating only 33 mW with g5V supplies.No reference current (IREF) trimming is required formost applications since the full scale output current is typicallyg1 LSB of 255 IREF/ 256. Relative accuracies of betterthan g0.19% assure 8-bit monotonicity and linearitywhile zero level output current of less than 4 mA provides8-bit zero accuracy for IREFt2 mA. The power supply currentsof the DAC0808 series are independent of bit codes,and exhibits essentially constant device characteristics overthe entire supply voltage range.The DAC0808 will interface directly with popular TTL, DTLor CMOS logic levels, and is a direct replacement for theMC1508/MC1408. For higher speed applications, seeDAC0800 data sheet.FeaturesY Relative accuracy: g0.19% error maximum (DAC0808)Y Full scale current match: g1 LSB typY 7 and 6-bit accuracy available (DAC0807, DAC0806)Y Fast settling time: 150 ns typY Noninverting digital inputs are TTL and CMOS compatibleY High speed multiplying input slew rate: 8 mA/msY Power supply voltage range: g4.5V to g18VY Low power consumption: 33 mW @g5V
