先选择ADC1给M4内核使用,如下所示,有IN0~IN19,表示19个通道,ADC1的通道0、6、7、8、9、13、14、15、17、19只能配置为单端模式,而其余通道可以配置为单端或者差分模式,本实验用到ADC1的通道19的单端输入,所以勾选IN19 Single-ended,我们没有使用硬件触发,使用的是软件触发,所以EXTI Conversion Trigger选项要D...
1)ADC_SINGLE_ENDED表示单端输入模式。2)ADC_DIFFERENTIAL_ENDED表示差分输入模式。 函数返回值:HAL_StatusTypeDef枚举类型的值。 3. HAL_ADC_ConfigChannel函数ADC通道配置函数,其声明如下: HAL_StatusTypeDef HAL_ADC_ConfigChannel(ADC_HandleTypeDef *hadc, ADC_ChannelConfTypeDef *sConfig); 函数描述:调用了HAL_...
pseudo-differential or fully-differential. The simplest method is to use a single-ended ADC when measuring single-ended signals. If a differential ADC is used to measure single-ended signals, simply connect the ADC AIN(-) pin to analog ground. This allows both single-ended and ...
Figure 2. Single-ended vs. fully-differential. Figure 3. AIN(+) and AIN(-) 180° out of phase. Another way to think about this is in relation to signal-to-noise ratio (SNR). The SNR is defined in termsof the ADC's full-scale input level and the minimum detectable signal: ...
A low-noise, wideband sample-hold amplifier (SHA) with differential outputs precedes the pipelined core, and accepts single-ended or differential inputs up to 5 V p-p. From the SHA's output, the signal path is fully differential. The first pipeline stage converts the 5 most significant ...
is used between the sensor and the ADC, this circuitry can affect the ADC input structure choice. Some ADCs are configurable, allowing selection between single-ended or pseudo-differential input structures (MAX186, MAX147) while others allow a choice between single-ended or fully-differential (...
For voltage input ADCs, three different input structure types exist: Single-Ended, Pseudo-Differential and Fully-Differential.The simplest solution is to select an ADC input structure that matches the sensor output. However, there are trade-offs with each structure that should be considered. In ...
This is because the two differential inputs can be 180° out of phase, as shown in Figure 3. Figure 2. Single-ended vs. fully-differential T/H指track-and-hold 全差分指对称,但共模 电压不一定非要为零 Vcom 不一定非要为0 .maxim-ic/an1108 Page 3 of 8 ...
