A17700
Pressure Sensor Interface and Signal Conditioning IC
with Polynomial Signal Compensation and Advanced Diagnostics
FEATURES AND BENEFITS DESCRIPTION • 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
applications
• PWM (Pulse Width Modulated) output with optional
diagnostics to identify fault conditions
• SENT (Single Edge Nibble Transmission) output
configurable for temperature or diagnostic reporting in
addition to pressure data
• Fast SENT provides increased data rates to support fast
response time applications
• Manchester interface for programming through single
