A17700 Overview
Key Specifications
Description
The A17700 is a sensor interface IC designed to connect directly to a strain gauge or other sensor in a Wheatstone bridge configuration. The A17700 amplifies and converts the analog input from the bridge to the digital domain, low-pass filters the signal, and outputs a ratiometric analog signal or a digital SENT/PWM protocol.
Key Features
- Directly interfaces with strain gauge or other transducer in Wheatstone bridge configuration for low noise and high accuracy measurements
- On-chip Poly(4,4) compensation for improved accuracy over temperature, compensating both IC and bridge
- Offering from Poly(1,1) to Poly(4,4) polynomial compensation including any possible degree between 0 and 4 like Poly(2,4) and Poly(3,3)
- Ratiometric analog output for legacy applications
- High bandwidth option to support fast response time
