The AD7813 is a high-speed, microprocessor-compatible,8-/10-bit analog-to-digital converter with a maximum throughputof 400 kSPS. The converter operates off a single 2.7 V to5.5 V supply and contains a 2.3 μs successive approximationA/D converter, track/hold circuitry, on-chip clock oscillator and8-bit wide parallel interface. The parallel interface is designed toallow easy interfacing to microprocessors and DSPs. The 10-bitconversion result is read by carrying out two 8-bit read operations.The first read operation accesses the 8 MSBs of the ADCconversion result and the second read accesses the 2 LSBs.Using only address decoding logic the AD7813 is easily mappedinto the microprocessor address space.
