ABSTRACT:
A bar graph decoder includes input terminals to which 5-bit digital data is input, a logic circuit for outputting a thermometer code changing continuously at a constant ratio in response to the input data, and output terminals connected to the logic circuit for outputting switch select signals according to the digital input. The logic circuit is configured only of 2-input OR circuits and 2-input AND circuits. As a result, a bar graph decoder having a simple configuration and a reduced number of elements can be provided.
