Application-Specific Sensors

Many applications require the use of some support electronics in addition to a digital or linear type of sensor. If an application presents a sufficiently high manufacturing volume for a sensor requiring auxiliary electronics, it is often cost-effective to integrate those electronics onto the IC along with the sensor. An integrated circuit targeted towards a particular application is usually referred to as an application-specific integrated circuit, or simply an ASIC. The geartooth sensors described in Chapter 8 are examples of ASICs designed to sense spinning targets. The ICs described in this chapter are all designed to solve particular and unique problems.
