A circuit for linearizing an analog-to-digital output with an analog signal V i, transmitted by an input circuit is applied to an input port of an analog-to-digital converter controlled by a sampling signal V s, to provide digital data V d on an "N" bit data bus. An analog-to-digital linearizing memory storing a look-up table of digital values, is coupled to a bus to receive the digital data V d, and to respond to the digital data V d by providing true linear digital values from the look-up table to a digital data processing system via an "N" bit data bus. A microprocessor is temporarily coupled between the output port of a converter and the input port of a memory via a bus, to serve as a switch between the bus and a programming memory containing a table of true linear digital values V t. A known test signal is applied to an input circuit, and true linear digital values V t stored in a programming memory, are then read into a linearizing memory to provide an accurate and reliable relation to a characteristic such as the amplitude of each step of the known test signal over the entire range of the known test signal.
