Motion sensors, including accelerometers, are electronic devices used to measure acceleration, velocity, angular rate and other related quantities. The PXLS80422AESR2 is a BiCMOS IC that uses capacitive sensors to measure acceleration. It has been designed for automotive and industrial applications that require a low-power, cost-effective, long-range and accurate motion detection solution.

The PXLS80422AESR2 has an array of capacitive accelerometer sensors that measure impact forces and vibration, such as shake, tilt and shock force. It is suitable for automotive and industrial applications such as machine monitoring, active safety, body-mounted ADAS systems and footprint recognition.

The chip uses an autocorrelator, a type of analog-to-digital converter (ADC) that converts time-domain signals into a linear representation. This is done by measuring the amplitude (height) of each cycle and computing the sum (integral) of all of them.

The accelerometer data is then converted to a frequency domain signal, using a complex frequency-to-time conversion process. The resulting signal can be streamed or streamed and stored, depending on the application.

The PXLS80422AESR2 has a number of features that make it ideal for automotive and industrial applications. It is ultra low power, meaning it consumes less energy and uses fewer components. It has a low noise level and high sensitivity, which makes it very effective at monitoring low-frequency motions.

The chip also features a wide-dynamic range, meaning it can accurately measure both high and low acceleration values. It can measure acceleration over a broad temperature range of –40°C to +105°C, making it suitable for a variety of environments.

The PXLS80422AESR2 also offers very fast response times, making it able to quickly detect and measure acceleration. It also features differential input at both ends, meaning it can accurately measure not only changes in acceleration, but also static acceleration.

The PXLS80422AESR2 is an excellent option for automotive and industrial applications that require accurate motion detection. Its low-power, low-noise, wide dynamic range, fast response time and differential input make it an ideal choice for applications such as machine monitoring, active safety, body-mounted ADAS systems and footprint recognition.
