Analog Devices Inc. AD7820KNZ

Description
The AD7820 is a high-speed, microprocessor-compatible 8-bit analog-to-digital converter (ADC) that utilizes a half-flash conversion technique to achieve a conversion time of 1.36 microseconds (µs). It operates with a single 5V supply and has an analog input voltage range of 0V to 5V.
The AD7820 features a built-in track-and-hold function, eliminating the need for an external sample-and-hold for signals with slew rates less than 100mV/s. It has latched, three-state output buffer circuitry for direct connection to a microprocessor data bus or system input port. An overflow output is also provided for cascading devices to achieve higher resolution.
