Sep 15, 2017 · Therefore, in choosing a reference voltage (V REF) the voltage output level and initial accuracy are of the first concern. V REF is also related to the resolution of the ADC. The resolution of an ADC is defined by dividing V REF by the total number of possible conversion values. The 16F877A is a capable microcontroller that can do many tasks because it has a large enough programming memory (large in terms of sensor and control projects) 8k words and 368 Bytes of RAM. This is enough to do many different projects. Apr 22, 2009 · Vref, along with the number of bits of accuracy, is the voltage that defines how large the individual voltage steps are between unique digital inputs. ADC can work with the Vin between GND and Vref, or -Vref and +Vref or however the manufacturer decides to make their part. Look at the data sheet for the part. It will be defined there.

The AD9461 is a 16-bit, monolithic, sampling, analog-to-digital converter (ADC) with an on-chip track-and-hold circuit. It is optimized for performance, small size, and ease of use. The AD9461 operates up to 130 MSPS, providing a superior signal-to-noise ratio (SNR) for instrumentation, medical imaging, and

ADC (Analog to Digital Converter) module is available with a number of dsPIC30/33 and PIC24 MCU modules. ADC is an electronic circuit that converts continuous signals to discrete digital numbers. ADC Library provides you a comfortable work with the module.

V CCA_ADC Supply voltage for ADC analog block — 2.375 2.5 2.625 V V CCINT Supply voltage for ADC digital block — 1.15 1.2 1.25 V (3) V CCIO for all I/O banks must be powered up during user mode because V CCIO I/O banks are used for the ADC and I/O functionalities. The integrated ADC subsystem consists of a three-channel analog input multiplexer (MUX) followed by a series gain amplifier (selectable 1x or 0.5x gain) and 10-bit SAR ADC. Serial-port-accessible ADC options allow the user to select VDDA or a different reference voltage applied to the VREF pin, set the programmable gain amplifier

PIC 16F877 series normally has five input/output ports. They are used for the input/output interfacing with other devices/circuits. Most of these port pins are multiplexed for handling alternate function for peripheral features on the devices. All ports in a PIC chip are bi-directional. When the ...

A With ADC, you're going to extract samples of water. For instance, you're going to put a little glass for 1 second under the pipe, every ten seconds. Doing the math, you'll be able to know the mean rate of flow. The faster you'll collect water, the more accurate the rate will be.
