DAC0808 8-Bit Multiplying Digital-to-Analog Converter IC

The DAC0808 was designed as an 8-bit monolithic digital-analog converter (DAC). This DAC IC features a full-scale output current settling time of 150 ns while dissipating only 33 mW with ±5V supplies. because the full-scale output current ranges typically ±1 LSB of 255 IREF/256, no reference current (IREF) trimming is important for many applications. Meanwhile, the Relative accuracies of higher than ±0.19% assure 8-bit monotonicity and linearity. While zero level output current of but 4 µA provides 8-bit zero accuracies for IREF>=2 mA.

The power supply currents of the DAC0808 independent of bit codes. And exhibits essentially constant device characteristics over the whole supply voltage range. The DAC0808 will interface directly with popular TTL, DTL or CMOS logic levels, and may be a direct replacement for the MC1508/MC1408. The chip accuracy of conversion is sweet and power consumption is additionally low to form it popular.

DAC0808 IC widely utilized in applications where a digital to analog conversion required. The chip wont to be popular a decade ago and its applications wont to be many but at the present there are many modern IC which may perform DAC with higher resolution, speed and also efficiency. The device inputs parallel 8 bit data from a microcontroller or microprocessor. And converts that data in to analog signal at the output. And therefore the analog output from DAC may be a current quantity and this needed to be converted in to voltage parameters for use in application easily. So to convert the present parameter in to voltage parameter we’ll use op-amp circuit. These op-amp circuits called a current-to-voltage converter. The output analog voltage from op-amp comes in linear relation with input digital value. Thus DAC conversion with DAC0808 obtained.
