Abstract: Mechanical misalignment and scaling factors lead to a mismatch between the values coming from a touchscreen panel (as translated by a touch screen controller) and the display (typically an LCD) on which the touch screenpanel is mounted. This tutorial discusses how to calibrate the touch screen panel to match the display.

Abstract: A perfect voltage reference produces a stable voltage independent of any external factors. Real-world voltagereferences, of course, are subject to errors caused by many external factors. One causeof these major errors istemperature. Without care, it is easy to operate a voltage reference outside its operating temperature range. Thisapplication note describes how references respond to temperature changes, and how self-heating can cause a voltagereference to operate outside its recommended temperature range. Once understood, this knowledge can then be used toavoid making this design error.

Abstract: Specifications such as noise, effective number of bits (ENOB), effective resolution, and noise-free resolution inlarge part define how accurate an ADC really is. Consequently, understanding the performance metrics related to noise isone of the most difficult aspects of transitioning from a SAR to a delta-sigma ADC. With the current demand for higherresolution, designers must develop a better understanding of ADC noise, ENOB, effective resolution, and signal-to-noiseratio (SNR). This application note helps that understanding.

Abstract: The MAX9930–MAX9933 family of RF controllers and detector can be used in a wide variety of applications. Anideal application is cable television (CATV) over fiber, where either a RF controller or a RF detector controls the gain of atransimpedance amplifier (TIA). This application note shows how the MAX9930 (RF controller) can be used as either theRF controller or detector.

如果明智地选择时钟，一份简单的抖动规范几乎是不够的。而重要的是，你要知道时钟噪声的带宽和频谱形状，才能在采样过程中适当地将它们考虑进去。很多系统设计师对数据转换器时钟的相位噪声和抖动要求规定得不够高，几皮秒的时钟抖动很快就转换成信号路径上的数分贝损耗。

所有MEMS麦克风都具有全向拾音响应，也就是能够均等地响应来自四面八方的声音。多个麦克风可以配置成阵列，形成定向响应或波束场型。经过设计，波束成形麦克风阵列可以对来自一个或多个特定方向的声音更敏感。麦克风波束成形是一个丰富而复杂的课题。本应用笔记仅讨论基本概念和阵列配置，包括宽边求和阵列和差分端射阵列，内容涵盖设计考虑、空间和频率响应以及差分阵列配置的优缺点。

Abstract: This application note presents an overview of the operational characteristics of accurate I²C real-time clocks (RTCs),including the DS3231, DS3231M, and DS3232. It focuses on general application guidelines that facilitate use of device resources forpower management, I²C communication circuit configurations, and I²C characteristics relative to device power-up sequences andinitializations. Additional discussions on decoupling are provided to support developing strategies for mitigating power-supply pushingof device frequency.
