If you manufacture or know of any other cheap FPGA development boards, please let me know so that I can include them on this list. I see from the Arduino blog and other sites that people have connected some even higher resolution ADCs to an to an Arduino board, including the 24-bit Linear LTC2440 ADC; the 18-bit LTC2400 ADC (24 bit at 5 samples per second); and the 24-bit ADC TI ADS1220. When I first started working with the Arduino platform (it was also my first experience with microcontrollers), I was a little surprised that analogWrite didn’t actually output a voltage, but a PWM (pulse-width modulated) signal. There are 4 good ways I can think of off the top of my head to improve your resolution. It can be purchased as a module for less than $1 on the web, but the module has a few problems and needs to be modified to interface with more general sensors and also for interfacing to the Raspberry Pi. When using a Raspberry Pi however, using a WS2811/WS2812 can be a little bit more challenging due to the strict timing needs. 9 mV) per unit. The output is created by the stable reference voltage, so it's doesn't vary if your power supply voltage changes slightly. 3V power supply if thats a consideration. Analog Devices has designed a high-resolution data acquisition chip for 4-20mA current loops around an ARM Cortex-M3 core. TI's complete end equipment solutions for audio applications integrate best in class systems expertise. I am using my Raspberry pi 3 and I am wondering if there is actually a 24 bit ADC chip compatible with the pi? I am going to use that ADC with LVDT sensor to measure a distance of 10mm in good precision. This module uses 24 high precision A/D converter chip hx711. Best 24 bit ADC converters. Better precision can be achieved by removing an inductor and providing your own precision reference.

A/D and Pic are connected by the serial line (mscl, sdi, sdo) and I use the SPI library to send and receive commands. but still delivering 12 digital & 8 analog I/O. for 24 bit one need a 32 bit long, and bytes are not abundant. Has an internal amplifier, adjustable from 1 to 128 times, While at the Shield of Arduino you should add it externally. 5V datum voltage source, using SPI interface communication protocol, data output rates up to 30ksps, support single-ended input and differential input. Very handy for measuring very small voltages - such as thermocouples, load cells, etc. Explore Deane Nathan's board "Analog to digital converter" on Pinterest. I've supplied code for the ATMega 1284 but it is untested. The MCU clock/IO line is 1 millimeter away from the ADC input trace; who would be so cramped for PCB area they would route a high-slew-rate clock/data trace only 1mm from a 18bit (or 24 bit) analog trace? How accurate is the EFI number? We assume parallel-plate coupling in the absence of any other mechanical geometry. 8 Channel and 4 Channel analog to digital converters for synchronized sampling of AC and DC signals.
