Overview

The conversion process and data acquisition are controlledusing standard control inputs, allowing easy interfacing tomicroprocessors or DSPs. The input signal is sampled on thefalling edge of CONVST, and conversion is also initiated atthis point. BUSY goes high at the start of conversion andgoes low 531.66 ns after falling edge of CONVST (AD7472with a clock frequency of 26 MHz) to indicate that the conversionis complete. There are no pipeline delays associatedwith the parts. The conversion result is accessed via standardCS and RD signals over a high speed parallel interface.

The analog input range for the part is 0 V to REF IN. The 2.5 Vreference is applied externally to the REF IN pin. The conversionrate is determined by the externally-applied clock.
