Description: scene brings higher performance and lower cost to new
markets. Figure 1 shows an example of how high speed
12-bit converters are becoming affordable for the first
time to a new range of applications. At the same time, the
new converters achieve better dynamic performance with
high frequency input signals. This means that more system
designers are facing the challenge of using high
performance ADCs. In this article, we will talk about some
of the problems designers encounter, how to recognize
their symptoms and how to avoid them. We will focus
on the particular case of the LTC1410, a 1.25Msps,
12-bit ADC. The same considerations become important
in higher resolution ADCs at lower speeds. Conversely,
lower resolution ADCs will need this same attention at
higher speeds.

Description: 本例展示了如何利用高级控制定时器（TIM1）来触发模数转换器（ADC）和利用自动注入转换功能来触发注入转换。
在每一个TIM1的上升沿，ADC对通道14（ADC Channel14）上的输入做一次规则转换，然后，DMA会将寄存器ADC_DR1中数据传送到内存中相应的表格。
使能自动注入转换功能，ADC能够在通道14的规则转换之后自动对通道11（ADC Channel11）上的输入做一次注入转换。随后产生一个ADC中断，并置标志位JEOC。在中断中将注入转换结果存入ADC_InjectedConvertedValueTab。
整个过程将重复32次，之后失能TIM1，ADC的转换也随之停止。
和示例1一样，为了使本示例能在STM3210B-LK1上运行，将通道14改为通道10，通道11则保持不变。并且选择结果列表（ADC_RegularConvertedValueTab和ADC_InjectedConvertedValueTab）中的2个数值把它们交替显示在LCD屏幕上。-This example shows how to use advanced control timer (TIM1) to trigger analog-to-digital converter (ADC) and the use of automatic injected conversion function to trigger the injected conversion. The rising edge of a TIM1, the ADC input on channel 14 (ADCs Channel14) do a rules conversion, then the DMA will register ADC_DR1 data to the corresponding table in the memory. Enable automatic injected conversion, the ADC can automatically input on channel 11 (ADCs Channel11) after conversion of the channel 14 of the rules once injected into the conversion. Subsequently generate an ADC interrupt, and set the flag JEOC. Interrupt will be injected into the conversion results deposited ADC_InjectedConvertedValueTab. The whole process will be repeated 32 times, followed by disability TIM1, the ADC conversion will stop. Example 1, this example can be run on the in the STM3210B-the LK1, channel 14 to channel 10, channel 11 will remain unchanged. And two values in the results list (ADC_

Description: The file give and explanation about analog to digital converter input noise. All analog-to-digital converters (ADCs) have a certain amount of
input-referred noise—modeled as a noise source connected in series
with the input of a noise-free ADC. Input-referred noise is not
to be confused with quantization noise, which is only of interest
when an ADC is processing time-varying signals. In most cases,
less input noise is better however, there are some instances where
input noise can actually be helpful in achieving higher resolution.
If this doesn’t seem to make sense right now, read on to find out
how some noise can be good noise-The file give and explanation about analog to digital converter input noise. All analog-to-digital converters (ADCs) have a certain amount of

Description: Sources of noise generation are pervasive in contemporary industrial applications.
Unwanted noise presents one of the major problems in measuring power or protecting
circuits in such an environment. Knowing the characteristics and understanding the
behavior of noise sources are valuable to designers and users of electronic circuits.

defines some fundamental concepts of electronic noise the latter portion addresses the
selection and design of filters used in conjunction with analog-to-digital converters
(ADCs). A design example for measuring voltage and current with dedicated
transformers, using the ADS8364, is provided along with equations and experimental

Description: Designing circuits using high-resolution ADCs (analog-to-digital converters) requires attention
to many details. One detail often overlooked is the input impedance of the ADC. This becomes
important as the output impedance of the source becomes high (e.g., when driven by a bridge
or an RTD). This application report explains how the input sampling works and how input
impedance can be calculated in the ADS1216, ADS1217, and ADS1218 family of ADCs.
