Signal Chain Overview
Typical sensor applications involve the monitoring of sensor
parameters and controlling of actuators. The sensor signal
chain, as shown below, consists of analog and digital
domains. Typical sensors output very low amplitude analog
signals. These weak analog signals are ampli?ed and ?ltered,
and converted to digital using op amps, an analog-to-digital
or voltage-to-frequency converter, and is processed at the
MCU. The analog sensor output typically needs proper signal
conditioning before it gets converted to a digital signal.
Typical Sensor Signal Chain Control Loop
The MCU controls the actuators and maintains the operation
of the sensor signal conditioning circuits based on the
condition of the signal detection. For the digital to analog
feedback path, the digital-to-analog converter (DAC), digital
potentiometer and Pulse-Width-Modulator (PWM) devices are
most commonly used. The MOSFET driver is commonly used
for the interface between the feedback circuit and actuators
such as motors and valves. Microchip offers a large portfolio
of devices for signal chain applications.
