DAC0808 8-bit DAC

DAC0808 is a 8-bit Digital to analog converter (DAC). It can be easily interfaced to Microcontrollers like Microchip's PIC series, 8051 series, Atmel's AVR microcontrollers. It can also be used with Arduino and Raspberry pi.

DAC0808 features 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 IREF≥2 mA. The power supply currents of the DAC0808 is 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.
