The AD7822BNZ is a 1-channel sampling Analog-to-digital Converter (ADC) with a maximum throughput of 2MSPS. It contains an on-chip reference of 2.5V, a track-and-hold amplifier, a 420ns, 8-bit half flash ADC and a high speed parallel interface. It combines the convert start and power-down functions at one pin, that is, the CONVST pin. This allows unique automatic power-down at the end of a conversion to be implemented. The logic level on the CONVST pin is sampled after the end of a conversion when an EOC signal goes high. If it is logic low at that point, the ADC is powered down. The parallel interface is designed to allow easy interfacing to microprocessors and DSPs. Using only address decoding logic, the parts are easily mapped into the microprocessor address space. The EOC pulse allows the ADCs to be used in a standalone manner.
