Pseudodifferential Multichannel Bridge Digitizer and Digital Cold Junction Compensation

Mar 15th 2000
This circuit enables pseudodifferential measurements of several bridge transducers and absolute temperature measurement. Consecutive readings are performed on each side of the bridge by selecting the appropriate channel on the LTC2428. Each output is digitized and the results digitally subtracted to obtain the pseudodifferential ...

Measuring Seven Platinum RTD Temperatures with One Reference Resistor and One Reference Current

Jun 25th 1997
The LTC2428 is a 8-channel 2.7V to 5.5V micropower 20-bit A/D converters with an integrated oscillator, 8ppm INL and 1.2ppm RMS noise. It uses a delta-sigma technology and provide single cycle digital filter settling time (no latency delay) for multiplexed applications. The first conversion after the channel is changed is ...
