Part Number:ADS124S08
Hello,
1.I want to know what data rate of ADS124S08 and what mode is in table 45 in datasheet.
2.What does "code flicker" mean in 10.2.2 Detailed Design Procedure?
and how to make the measurement result on table 45 with no code flicker ?
The key considerations in the design of a 3-wire RTD circuit are the accuracy, the lead wire compensation, and the sensor self-heating. As the design values of Table 45 show, several values of excitation currents are available. The resolution is expressed in units of noise-free resolution (NFR). Noise-free resolution is resolution with no code flicker. The selection of excitation currents trades off resolution against sensor self-heating. In general, measurement resolution improves with increasing excitation current. Increasing the excitation current beyond 1000 µA results in no further improvement in resolution for this example circuit. The design procedure is based on a 500-µA excitation current, because this level of current results in very low sensor self-heating (0.4 mW).
Many Thanks,
Willy
