Abstract: This application note shows how to configure various loopback modes of the DS31256 HDLC controller, and how to verify and troubleshoot as necessary. IntroductionThis application note highlights the de...

Abstract: This application note provides an example of how to configure a single T1 port on DS31256 HDLC Controller in Bridge mode. A coding example is discussed step by step for easy adaptation to end user applications to understand how t...

Abstract: The Dallas Semiconductor Ethernet link transport engine (ELITE) product line was created to bridge WAN to LAN. The ELITE products can be configured in several ways, the most common of which is through microprocessor (µP) co...

The C-message filter, which simulates the frequency response of the human ear, is a commonly specified test and measurement filter for voice, audio, and telecomunication applications in the U.S. In Europe, a close relative is a psophometri...

Abstract: Systems with multiple "hot spots" often require several temperature sensors or temperature switches. This application note discusses the use of temperature sensors with analog, digital, and PWM interfaces in such systems. ...

Abstract: Temperature is an analog quantity, but digital systems often use temperature to implement measurement, control, and protection functions. If you apply the right techniques and components, the necessary conversion of analog temper...

The MAX1298/MAX1299 analog-to-digital converters with an internal temperature sensor have a guaranteed ±1°C accuracy over the extended temperature range (-40°C to 85°C), the best temperature-sensor accuracy over this range of any part ...

Abstract: This application note describes a low-cost circuit that can detect when a chassis fan filter has become clogged with dust. It does this by using a temperature sensor to determine the rate of cooling of a transistor in the air pat...
