Abstract: This application note discusses the some of the benefits of digital calibration and shows common calibration circuits by application.
Calibration makes products accurate, safe, and affordable. It allows manufacturers to deliver "perfect" devices at competitive prices. Maxim's large variety of digital calibration parts enables quick automated testing and adjustment.
These ideas are presented pictorially to save time and speed comprehension. Most engineers will spend a second or two on each block until one fits their application. They can then click on the diagram to jump to the source application note or datasheet for more information.
Electronic calibration can reduce cost in many areas. It can remove manufacturing tolerances, specify less-expensive components, reduce test time and customer returns, and improve reliability. It also increases customer satisfaction, lowers warranty costs, and speeds product delivery.
Digitally controlled calibration devices and potentiometers (pots) are replacing mechanical pots in many products. By removing human error, these parts reduce test time and expense. Additionally, digital devices are insensitive to vibration, dust, dirt, and moisture, which can cause failure in mechanical pots. The increased reliability can reduce product liability concerns and improve product safety. Furthermore, the small size of electronic calibration devices benefits small board layouts and portable devices.
This application note shows some of the more common calibration circuits by application. More calibration design tips and tools are available at www.maximintegrated.com/cal.
