2.1 Ratiometric RTD measurement in heat meters

Description

April 9, 2018

Precision 24-bit DS ADCs are gaining traction in the heat and cold meter market as they achieve higher temperature measurement resolution and accuracy than the traditional Slope ADC approach, found in many ultrasonic analog front end devices. The ADS1220 DS ADC family supports multiple 2-wire or 4-wire PT sensors and allows the trade-off between power consumption versus resolution and accuracy. The fast start-up time enables the power duty cycling of these devices, and the low power consumption makes them suitable for battery-powered meters.
