Low-Cost 8-Bit Monolithic ADC Converts in 1.36 µs max

AD7820 Includes Track-Hold Function, 4-4 Flash Conversion with Subranging, Has Fully Specified Max Conversion Time for All Modes & Temperature Ranges

The monolithic AD7820 is a fast, µP-compatible, 8-bit ratiometric a/d converter housed in a narrow (0.3") 20-pin DIP. It employs two 4-bit "flash" a/d converters and a 4-bit d/a converter in a subranging configuration to provide a fast maximum conversion time of 1.6µs over temperature—1.36µs max at 25°C—when conversion is started by a Write command. Read full article
