AD7819YNZ (ANALOG DEVICES)

The AD7819YNZ is a 8-bit sampling Analog-to-digital Converter (ADC) with a maximum throughput of 200kSPS. The converter operates off a single 2.7 to 5.5V supply and contains a 4.5µs 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. Using only address decoding logic the converter is easily mapped into the microprocessor address space. When used in its power-down mode, the converter automatically powers down at the end of a conversion and powers up at the start of a new conversion. This feature significantly reduces the power consumption of the part at lower throughput rates. It can also operate in a high speed mode where the part is not powered down between conversions. In this mode of operation the part is capable of providing 200kSPS throughput.
