Austriamicrosystems Introduces a New Sensor Interface Specifically for Automotive Unbiased Capacitive Sensors
The AS1716 sensor interface combines all of the necessary analoge functions in one chip to provide a fully flexible interface for Piezo Electronic sensors. Although designed with automotive knock sensors in mind the microchip is also configurable for industrial sensor applications
Unterpremstaetten, Austria (November 16, 2009) - austriamicrosystems (SIX: AMS), a leading global designer and manufacturer of high performance analog ICs for communications, industrial, medical and automotive applications expanded its interface product portfolio with the AS1716, a sensor designed for interfacing to Piezo Electronic capacitive sensors.
"Piezo Electronic sensors have many advantages over other sensor types. They are self generating and need no external excitation and they are compact and have excellent linearity" said Bruce Ulrich, Marketing Director Consumer & Communications at austriamicrosystems. "In Automotive Engine designs the knock sensor is an integral part of the engine management system helping to increase overall reliability and improve fuel efficiency. The AS1716 provides the automotive customer with a complete flexible differential to a single ended solution."
The AS1716 operates from a single supply 4.5V to 5.5V. The device provides differential inputs, a first order low pass filter to cut off the high frequency noise components, differential to single ended conversion, programmable gain stage and a two pole low pass multiple feedback filter. The AS1716 is an analog front end specifically designed for unbiased capacitive sensors, interfacing with sample and hold input stages and analog digital converters.
The device has been EMC characterized by IEC 61967-4 (1Ohm / 150Ohm Method) by IEC 62132-4 (Direct Power Injection), is automotive qualified to AECQ100 for IC and PPAP level 3 and comes in an 8-pin SOIC Package.
