description
The AD7524M is an Advanced LinCMOS 8-bit
digital-to-analog converter (DAC) designed for
easy interface to most popular microprocessors.
NC–No internal connection
The AD7524M is an 8-bit multiplying DAC with input latches and with a load cycle similar to the write cycle 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 AD7524M provides 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, the AD7524M interfaces easily to most microprocessor
buses or output ports. Excellent multiplying (2 or 4 quadrant) makes the AD7524M an ideal choice for many
microprocessor-controlled gain-setting and signal-control applications.
The AD7524M is characterized for operation from –55°C to 125°C.
