Frequently Asked Questions
How does the AC excitation feature of PADS1261IRHBT reduce measurement errors in RTD circuits?
The PADS1261IRHBT AC excitation alternates current direction through the RTD at a fixed frequency, cancelling offset errors and thermoelectric EMF contributions from lead resistance. This improves measurement accuracy compared to DC excitation, particularly in 2-wire RTD configurations over long cable runs in factory environments.
What ADC resolution and maximum sample rate does the PADS1261IRHBT provide for industrial sensor digitization?
The PADS1261IRHBT provides 24-bit resolution at output data rates up to 40 kSPS, delivering a dynamic range suitable for digitizing low-level signals from strain gauges and load cells while resolving micro-volt level differences critical in precision weighing and force measurement applications.
How many differential input channels does the PADS1261IRHBT support for multi-sensor data acquisition?
The PADS1261IRHBT supports 10 differential input channels, allowing a single device to scan up to 10 independent sensor signals. This multi-channel capability eliminates the need for external multiplexers in many factory automation data acquisition designs, reducing board complexity.
Is the PADS1261IRHBT suitable for use in industrial temperature ranges and what package does it use?
The PADS1261IRHBT is rated for industrial temperature operation from -40°C to 125°C and comes in a compact QFN package (RHB). This rating and package make it appropriate for harsh factory floor installations where ambient temperatures and humidity levels exceed consumer-grade limits.
