An 8-bit DAC with input latches, the load cycle of the AD7524-EP Excellent multiplying characteristics (2- or 4-quadrant) make is similar to the write cycle of the random access memory. Using the AD7524-EP an ideal choice for many microprocessor an advanced thin-film on the CMOS fabrication process, the controlled gain setting and signal control applications. AD7524-EP provides accuracy to LSB with a typical power Additional application and technical information can be found dissipation of less than 10 mW. in the AD7524 data sheet. An improved design eliminates the protection Schottky previously required and guarantees TTL compatibility when using a 5 V supply. The loading speed has also been increased for compatibility with most microprocessors. Rev. A Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
