Description
- DC1410A-B, 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 ADC with ten selectable speed/resolution modes from 6.9Hz/200nVRMS to 3.5kHz/23 uVRMS (4kHz with external oscillator). Key DC specifications include 5ppm INL, 5uV offset, 10ppm full-scale error and 20nV/degree-C offset drift. In the 6.9Hz/200nVRMS mode, input normal mode rejection of 50Hz and 60Hz noise is better than 80dB
