The project described here is a two-channel ultra-precise, current-sense amplifier that can measure voltage drops across shunt resistors over a wide common-mode range from 2.7 V to 120 V. The INA2290A1 chip is the heart of the project. The ultra-precise current measurement accuracy is...

This single-supply, low-side, current sensing solution accurately detects load current between 0 and 1A. The current sensor measures 0 to 1A across the shunt resistor, providing 0 to 4.9V output. The OPA320 features wide bandwidth and low offset voltage making it an excellent...

The R-2R Digital-to-Analogue Converter is a type of data converter that transforms a digital binary number into an analog output signal that is proportionate to the value of the digital number using two precision resistors. The binary-weighted digital-to-analog converter, in contrast...

Analog to Digital Converter An analog-to-digital converter (ADC) is an electronic circuit that is used to convert a real-world signal into a digital or binary code. Real-world signals are usually taken from a sensory system which are generally analog in nature and represent instantaneous...

OpenPLC is a fully-featured standardized Programming Logic Controller Suite that officially supports a variety of platforms such as Arduino, Raspberry Pi 2/3/4, Windows, and Linux. This openPLC consists of two main parts named the Runtime software and the programming Editor. While you...

Introduction Essentially, signals are functions that can be classified into different categories. A signal can be either continuous or discrete, and it can be either periodic or non-periodic. In our ‘Analog to digital conversion’ series of articles, we have seen that it is always...

Transmission Gate A transmission gate is a form of a bilateral switch constructed using Metal Oxide Field Effect Transistors (MOSFETs) that can be externally controlled through logic levels. A switch, analog one to be precise, controls the passage of analog signals through it and is a...

The circuit shown here is a high-side voltage-to-current (V-I) converter. It translates an input voltage of 0 V to 2 V to an output current of 0 mA to 100 mA. The low offset voltage and offset drift of the OPA2333 facilitate excellent DC accuracy for the circuit. The project...
