The converter operates off a single +2.7 V to +5.5 V supply and contains a 2.3 µs successive approximation A/D converter, track/hold circuitry, on-chip clock oscillator and 8-bit wide parallel interface. The parallel interface is designed to allow easy interfacing to microprocessors and DSPs. The 10-bit conversion result is read by carrying out two 8-bit read operations. The first read operation accesses the 8 MSBs of the ADC conversion result and the second read accesses the 2 LSBs. Using only address decoding logic the AD7813 is easily mapped into the microprocessor address space. When used in its power-down mode, the AD7813 automatically powers down at the end of a conversion and powers up at the start of a new co.
