Bridge Reversal Eliminates 1/f Noise and Offset Drift of a Low Noise, Non-Autozeroed, Bipolar Amplifier

Sep 13th 1999
This circuit gives 14nV noise level (or 19 effective bits) over a 10mV span. Bridge reversal eliminates 1/f noise and offset drift of a low noise, non-autozeroed, bipolar amplifier. The LTC2440 is a high speed 24-bit No Latency delta sigma ADC with 5ppm INL and 5μV offset. It uses proprietary delta-sigma architecture enabling ...
