AD7524

a FEATURES Microprocessor Compatible (6800, 8085, Z80, Etc.) TTL/CMOS Compatible Inputs On-Chip Data Latches Endpoint Linearity Low Power Consumption Monotonicity Guaranteed (Full Temperature Range) Latch Free (No Protection Schottky Required) APPLICATIONS Microprocessor Controlled Gain Circuits Microprocessor Controlled Attenuator Circuits Microprocessor Controlled Function Generation Precision AGC Circuits Bus Structured Instruments CMOS 8-Bit Buffered Multiplying DAC AD7524 FUNCTIONAL BLOCK DIAGRAM GENERAL DESCRIPTION The AD7524 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 AD7524’s load cycle is similar to the “write” cycle of a random access memory. Using an advanced thin-film on CMOS fabrication process, the AD7524 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 AD7524 interfaces directly to most microprocessor buses or output ports. Excellent multiplying characteristics (2- or 4-quadrant) make the AD7524 an ideal choice for many microprocessor controlled gain setting and signal control applications.
