I am using the ADC on CC2640. And I have two questions about it. 1. What is the maximum input if Fixed reference is used and scaling is enabled? Chapter 5.1 Absolute Maximum RatingsinCC2640 SimpleLink™ Bluetooth® Smart Wireless MCU(page 13) indicates that ...
Voltage Reference Overview for ADC This video covers reference specifications to gain a deeper understanding of how the voltage reference impacts the performance of the ADC system. Video Video Important Parameters of a Voltage Reference This video will review the most important parameters in a VREF an...
If an external voltage is provided through VREFP/VREFN, there are some accuracy parameter about the voltage supply such as the device REF3233, High Accuracy is 0.01%, shown as below. When VDDA_ADC, the internal reference is used, what's the high accuracy? For example if REF3233 0.01% is...
判断满充条件参数 ->Charge Voltage 满充充电电压,charger恒压充电时电压 ->Taper Current 满充时电流,一般设置比charger停止充电时电流略大25mA左右(注意BQ27425,BQ27421/441填写方式略有不同,换算数值为Taper current(数值)=Design Capacity*10/Taper current(mA)) ->Taper Voltage 用于判断电池符合满充的条件,...
and the ADC16V130 could be re-calibrated at any time by asserting and then de-asserting power-down. An integrated low noise and stable voltage reference and differential reference buffer amplifier easies board level design. On-chip duty cycle stabilizer with low additive jitter allows wide duty ...
Voltage = (ADC Value / ADC Resolution) * Reference Voltage 复制代码 在本文中，我们已经知道微控制...
