This design idea shows how to adjust any three-terminal voltage reference using a resistor, a current sink/source, and a buffer amplifier to dynamically calibrate the reference, fine-tune its output value, or generate a slightly different value. http://www.maxim-ic.com/app-notes/index.mvp/id/5083 Tue, 15 May 2012 00:00:00 -0000 http://www.maxim-ic.com/app-notes/index.mvp/id/4648 The MAX4951BE SATA I/II/III bidirectional redriver features input equalization, preemphasis, and two new low-power modes. This device allows long runs of FR-4 or flex cable to be part of the system, which still meets required eSATA compliance points. The MAX4951BE overcomes the issues of matching a SATA host to an eSATA external connection. http://www.maxim-ic.com/app-notes/index.mvp/id/4648 Tue, 15 May 2012 00:00:00 -0000 http://www.maxim-ic.com/app-notes/index.mvp/id/5223 This application note describes how to design hardware for a temperature-based heating system for a vehicle that has an engine preheater installed, based on ambient temperature and a preordained engine start time. This system can also be used for other purposes, such as turning on a storage heater if the ambient temperature falls below a preordained value. http://www.maxim-ic.com/app-notes/index.mvp/id/5223 Mon, 14 May 2012 00:00:00 -0000 http://www.maxim-ic.com/app-notes/index.mvp/id/5150 This design idea shows how you can design a simple wireless temperature-monitoring system with data-logging capabilities by using a local temperature sensor and an ASK transmitter and receiver pair. http://www.maxim-ic.com/app-notes/index.mvp/id/5150 Mon, 14 May 2012 00:00:00 -0000 http://www.maxim-ic.com/app-notes/index.mvp/id/5403 The 1-Wire product family includes numerous devices that can be easily evaluated using a Windows&reg;-based PC with a USB port and free demo software from Maxim's website.

The example presented in this article uses the Rowley CrossStudio for the MAXQ30 compiler to demonstrate how the MAXQ1050 can read a smart card. http://www.maxim-ic.com/app-notes/index.mvp/id/5393 Mon, 14 May 2012 00:00:00 -0000 http://www.maxim-ic.com/app-notes/index.mvp/id/5074 This design idea explains how to implement an 8-bit analog-to-digital converter (ADC), using a microcontroller and some common components. http://www.maxim-ic.com/app-notes/index.mvp/id/5074 Fri, 11 May 2012 00:00:00 -0000 http://www.maxim-ic.com/app-notes/index.mvp/id/4713 If sensitive analog systems are run from one supply without the sufficient bypassing to eliminate noise, undesired degradation in a system's performance will result. This application note provides insight into suitable techniques to overcome this roadblock. http://www.maxim-ic.com/app-notes/index.mvp/id/4713 Fri, 11 May 2012 00:00:00 -0000 http://www.maxim-ic.com/app-notes/index.mvp/id/5404 This reference design provides a complete demonstration platform for using industrial/scientific/medical radio frequency (ISM-RF) products in an automatic meter reading (AMR) application. This document includes the hardware, firmware, and system structure requirements for implementing an AMR design that demonstrates operation with a physical water meter. http://www.maxim-ic.com/app-notes/index.mvp/id/5404 Fri, 11 May 2012 00:00:00 -0000 http://www.maxim-ic.com/app-notes/index.mvp/id/5405 For many first-time users, finding the right logger that meets their needs can be a challenging task. In simple language, this tutorial explains logger <u>i</u>Buttons and their applications and accessories. It also discusses logger <u>i</u>Buttons' primary and special features, as these can be critical factors in making the right choice. http://www.maxim-ic.com/app-notes/index.mvp/id/5405 Fri, 11 May 2012 00:00:00 -0000 http://www.maxim-ic.com/app-notes/index.mvp/id/4672 This application note analyzes the external influences that introduce error to a precision digital-to-analog converter (DAC). Focus will be on temperature drift. This error is recognized as part of a DAC's error budget. The article discusses the error factors introduced by both the data converter and the voltage reference. After understanding the sources of error, it then provides the calculations required to specify the data converter and that will compensate for the error and meet a system's target specifications. The calculations are available in an Excel spreadsheet.<br><br> This applications note focuses on Maxim's 3-terminal voltage references and precision DACs. Voltage references and DACs have many specifications, but only those relevant to the error budget will be discussed. http://www.maxim-ic.com/app-notes/index.mvp/id/4672 Thu, 10 May 2012 00:00:00 -0000 http://www.maxim-ic.com/app-notes/index.mvp/id/4666 This application note describes and compares two key-scan methods commonly used in smartphone key pads. It shows the benefit of eliminating the use of EMI filters for the low EMI method. The capacitive loading allowance associated with the ESD protection diode is also estimated. http://www.maxim-ic.com/app-notes/index.mvp/id/4666 Thu, 10 May 2012 00:00:00 -0000 http://www.maxim-ic.com/app-notes/index.mvp/id/4419 A perfect voltage reference produces a stable voltage independent of any external factors. Real-world voltage references, of course, are subject to errors caused by many external factors. One cause of these major errors is temperature. Without care, it is easy to operate a voltage reference outside its operating temperature range. This application note describes how references respond to temperature changes, and how self-heating can cause a voltage reference to operate outside its recommended temperature range. Once understood, this knowledge can then be used to avoid making this design error. http://www.maxim-ic.com/app-notes/index.mvp/id/4419 Wed, 09 May 2012 00:00:00 -0000 http://www.maxim-ic.com/app-notes/index.mvp/id/4230 The MAX9930&#8211;MAX9933 family of RF controllers and detector can be used in a wide variety of applications. An ideal application is cable television (CATV) over fiber, where either a RF controller or a RF detector controls the gain of a transimpedance amplifier (TIA). This application note shows how the MAX9930 (RF controller) can be used as either the RF controller or detector. http://www.maxim-ic.com/app-notes/index.mvp/id/4230 Wed, 09 May 2012 00:00:00 -0000 http://www.maxim-ic.com/app-notes/index.mvp/id/5384 Specifications such as noise, effective number of bits (ENOB), effective resolution, and noise-free resolution in large part define how accurate an ADC really is. Consequently, understanding the performance metrics related to noise is one of the most difficult aspects of transitioning from a SAR to a delta-sigma ADC. With the current demand for higher resolution, designers must develop a better understanding of ADC noise, ENOB, effective resolution, and signal-to-noise ratio (SNR). This application note helps that understanding. http://www.maxim-ic.com/app-notes/index.mvp/id/5384 Mon, 07 May 2012 00:00:00 -0000
