Keywords:signal processing? interface? sensor?

The TPIC8101 is a dual-channel, signal processing IC for detection of premature detonation in combustion (gasoline) engines. This device 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, clock synchronization frequency, and sampling rate control of on-board ADC and DAC in signal processing chain. These features allow the TPIC8101 to be a flexible interface that can adapt to cost and/or processing time constraints of the customer.
