Product Summary

The AD7524BQ is a low cost, 8-bit monolithic CMOS DAC designed for direct interface to most microprocessors. Basically an 8-bit DAC with input latches, the AD7524BQ load cycle is similar to the write cycle of a random access memory. Using an advanced thin film on CMOS fabrication process, the AD7524BQ provides accuracy to 1/8 LSB with a typical power dissipation of less than 10 milliwatts. A newly improved design eliminates the protection Schottky previously required and guarantees TTL compatibility when using a +5 V supply. Loading speed has been increased for compatibility with most microprocessors. Featuring operation from +5 V to +15 V, the AD7524BQ interfaces directly to most microprocessor buses or output ports. Excellent multiplying characteristics (2- or 4-quadrant) make the AD7524BQ an ideal choice for many microprocessor controlled gain setting and signal control applications.
