Additional Details

The ADC0838BCN uses a successive approximation conversion technique to convert analog input voltage to digital output code. The on-chip multiplexer selects one of the eight analog input channels, which is then sampled and held by the internal track and hold circuitry. The conversion process is initiated by applying a start pulse, and the end of conversion (EOC) signal indicates the completion of the conversion. The digital output is available in a parallel format, allowing for easy interface with microprocessors and other digital systems. The typical conversion time is 100 μs. The device operates from a single 5V supply and typically consumes 15 mW of power. The package is a 20-pin DIP.
