TIDA-00152, Automotive Acoustic Knock Sensor Interface
Reference design by: Texas Instruments
TIDA-00152, Reference Design utilizes a dual-channel, signal processing IC for detection of premature detonation in combustion (gasoline) engines. The heart of this design is the TPIC8101 that serves as an interface between acoustical sensors or accelerometers and automobile engine management systems. Programmable features on this device include the selection of engine knock detection sensitivity, engine resonance frequency and sampling rate control of on-board ADC and DAC in signal processing chain
