ADI launches FET input analogue front end

Analog Devices has introduced a  FET input AFE (analog front-end) with an integrated ADC driver designed to interface directly with current mode sensors such as photo diodes and highoutput impedance-voltage sensors. The ADA4350 integrates a FET input amplifier, switching network and ADC driver into a single package, which simplifies design and lowers power and PCB footprint by more than 50 percent compared ...

Input programming activity

The previous activities showed you how to make the microcontroller activate outputs. This activity demonstrates how to receive inputs from externally connected devices. The input programs also introduce the concept of abstraction—the ability of a program to refer to I/O circuits using assigned variable names rather than their specific hardware addresses. What you should know before starting CHRP related inf ...

Lab 2: Basic digital input and output

Description Today we will learn how to read digital inputs from a push button switch. A digital input has only two values: 1 and 0. The configuration of the push button switch is same as that of the reset switch except it goes to a different port pin. The status of the switch will be read through RC1 and every time when it is pressed, an LED connected to RC0 will be toggled ON and OFF. Required Theory You m ...

How To Use PIC Microcontroller For Voice Input And Output

Microcontrollers are purely digital devices which work on logic0 and logic1 voltages; still they are widely used for analog signal processing. There are specialized signal processors chips available which are custom made for particular applications; however a general purpose microcontroller is more than enough for small kind of signal processing applications like audio signal input and output. The microcont ...
