  Digital-to-analog converters (DACs) are prevalent inindustrial control and automated test applications.General-purpose automated test equipment often requiresmany channels of precisely controlled voltagesthat span several voltage ranges. The LTC2704 is ahighly integrated 16-bit, 4-channel ...

  The 14-bit LTC2351-14 is a 1.5Msps, low power SARADC with six simultaneously sampled differential inputchannels. It operates from a single 3V supply and featuressix independent sample-and-hold amplifi ers and a singleADC. The single ADC with multiple S/HAs enables excellentrange match (1m ...

  Many 8-bit and 16-bit microcontrollers feature 10-bitinternal ADCs. A few include 12-bit ADCs, but these oftenhave poor or nonexistent AC specifi cations, and certainlylack the performance to meet the needs of an increasingnumber of applications. The LTC®2366 and its slowerspeed versi ...

The STM32F10xxx microcontroller family embeds up to three advanced 12-bit ADCs (depending on the device) with a conversion time down to 1 μs. A self-calibration feature is provided to enhance ADC accuracy versus environmental condition changes.

  　　ADC制造商在数据手册中定义ADC性能的方式令人困惑，并且可能会在应用开发中导致错误的推断。最大的困惑也许就是“分辨率”和“精确度”了——即Resolution和Accuracy，这是两个不同的参数，却经常被混用，但事实上，分辨率并不能代表精确度，反之亦然。本文提出并解释了ADC&l ...

  　　模拟转换器性能不只依赖分辨率规格 　　大量的模数转换器(ADC)使人们难以选择最适合某种特定应用的ADC器件。工程师们选择ADC时，通常只注重位数、信噪比(SNR)、谐波性能，但是其它规格也同样重要。本文将介绍ADC器件最易受到忽视的九项规格，并说明它们是如何影响ADC性能的。 　　1. SNR比分辨率更为重 ...

Differential Nonlinearity: Ideally, any two adjacent digitalcodes correspond to output analog voltages that are exactlyone LSB apart. Differential non-linearity is a measure of theworst case deviation from the ideal 1 LSB step. For example,a DAC with a 1.5 LSB output change for a 1 LSB digital codec ...

运行典型高速ADC评估板设置

采用高输入频率、高速模数转换器(ADC)的系统设计是一项具挑战性的任务。ADC输入接口设计有6个主要条件：输入阻抗、输入驱动、带宽、通带平坦度、噪声和失真。
