4.99kΩ 33Ω 4.99kΩ VINB a 5.7 If the input to the ADC is coming from a long coaxial cable run, it may be desirable to buffer the transient currents at the ADC inputs from the cable to prevent problems resulting from reflections, especially if the cable is not source-...
Buffer communication if the EIE bit is set.Bit 1 FE: Framing errorThis bit is set by hardware when a de-synchronization, excessive noise or a break characteris detected. It is cleared by a software sequence (an read to the USART_SR registerfollowed by a read to the USART_DR register)....

It’s the easiest way in code in order to perform an analog to digital conversion using the ADC on an analog input channel. However, it’s not an efficient way in all cases as it’s considered to be a blocking way of using the ADC. As in this way, we start the A/D conversion ...

– Integrated ADC driver – Integrated precision reference – Common-mode voltage output buffer • High performance: – 18-bit no-missing-codes – INL: ±1LSB, DNL: ±0.75LSB – SNR: 95.5dB and 104.5dB SNR wit
It employs a capacitive charge pump and a comparator-controlled charging buffer to realize the residue amplification.The circuit is differential andthecommon-modeinput is rejected at the output, althoughno active common-mode feedbackcircuit is used. In principle, this technique eliminates static power...
