8-BIT MULTIPLYING DIGITAL-TO-ANALOG CONVERTERS

The TLC7524C TLC7524E and TLC7524I are CMOS, 8-bit, digital-to-analog converters (DACs) designed for easy Interface to most popular Microprocessors The devices are 8-bit, multiplying DACs with input Latches and load cycles similar to the write cycles of a random access memory. Segmenting the high-order bits minimizes glitches during changes in the most significant bits, which produce the highest glitch impulse. The devices provide accuracy to 1/2 LSB without the need for thin-film resistors or laser trimming, while dissipating less than 5 mW typically. Featuring operation from a 5-V to 15-V single supply, these devices Interface easily to most Microprocessor buses or output ports. The 2- or 4-quadrant multiplying makes these devices an ideal choice for many microprocessor-controlled gain-setting and signal-control applications. The TLC7524C is characterized for operation from 0C to 70C. The TLC7524I is characterized for operation from 25C to 85C. The TLC7524E is characterized for operation from 40C to 85C.
