Description
- TIPD152, Hardware-Compensated Ratiometric 3-Wire RTD System Reference Design. This Precision Verified Design implements a hardware compensated 3-wire RTD acquisition system that accurately measures temperature from 0 to 100. The voltage input and reference voltage are placed in a ratiometric configuration in order to reduce the errors from noise and drift and improve overall system accuracy. The ADS1247 simplifies the front-end solution through integration of the required current sources, programmable gain amplifier, and digitally-controlled multiplexer in to one chip. A unique chopping technique is used to minimize any difference between the two current sources
