In electronics, a digital-to-analog converter (DAC, D/A, D2A, or D-to-A) is a system that converts a digital signal into an analog signal.An analog-to-digital converter (ADC) performs the reverse function.. There are several DAC architectures; the suitability of a DAC for a particular application is determined by figures of merit including: resolution, maximum sampling frequency and others.

Algorithm. The successive-approximation analog-to-digital converter circuit typically consists of four chief subcircuits: . A sample-and-hold circuit to acquire the input voltage V in.; An analog voltage comparator that compares V in to the output of the internal DAC and outputs the result of the comparison to the successive-approximation register (SAR).; A successive-approximation …

An ammeter (abbreviation of Ampere meter) is a measuring instrument used to measure the current in a circuit.Electric currents are measured in amperes (A), hence the name. The ammeter is usually connected in series with the circuit in which the current is to be measured. An ammeter usually has low resistance so that it does not cause a significant voltage drop in the circuit …

Types. The basic difference between various types of converters or inverters is that they vary in their nature and the devices they support. Analog-to-digital converter (ADC) is a device that converts the input analog voltage to a digital number proportional to the magnitude of the voltage or current. Some non-electronic or partially electronic devices, like rotary encoders, can be …
