DC1410A-B - LTC2449 Demo Board | Load Cell Digitizer Application, req DC2026C
Demonstration circuit 1410A shows a compact, high resolution solution for measuring Wheatstone bridge type sensors for load, pressure, temperature, acceleration, and many other physical quantities.
Assembly type B features the LTC2449, an 8-/16-channel, high speed, 24-bit Δ∑ ADC with ten selectable speed/resolution modes from 6.9Hz/200nVRMS to 3.5kHz/23μVRMS (4kHz with external oscillator). Key DC specifications include 5ppm INL, 5μV offset, 10ppm full-scale error and 20nV/°C offset drift. In the 6.9Hz/200nVRMS mode, input normal mode rejection of 50Hz and 60Hz noise is better than 80dB.

Linduino
Linduino is an Arduino compatible platform for developing and distributing firmware libraries and code for SPI and I²C-compatible integrated circuits. The Linduino One board interfaces to more than 300 QuikEval demonstration cards, supporting a variety of product types including analog-to-digital converters (ADCs), digital-to-analog converters (DACs), power monitors, and more. Firmware libraries for individual devices are written in C and designed to be portable to a wide variety of processors and microcontrollers. Each library has a demonstration program that can be uploaded to the Linduino One platform to allow the circuit and software to be quickly and easily verified.
