This clever Analog-to-Digital Converter (ADC) has been at the heart of the Digital Volt Meter (DVM) for decades. When a dual-slope AID converter is used for a DVM the counters may be decade rather than binary and the segment and digit drivers may be contained in the chip. Tim Wilmshurst, in Designing Embedded Systems with PIC Microcontrollers (Second Edition), 2010. If the ADC performs the analog to digital conversion directly by utilizing the internally generated equivalent digital (binary) code for comparing with the analog input, then it is called as Direct type ADC . So far, we’ve only been able to escape the sheer volume of components in the flash converter by using a DAC as part of our ADC circuitry. Analog to digital converters. Dual Slope ADC. Dual slope.
