WebOct 27, 2010 · The gained signal is given to the ADC and the ADC data is later processed by the microprocessor system. Below is the equation to calculate the current from the ADC conversion results: Input Current to be measured: 4mA. Gain of Differential amplifier: 10. ADC Supply voltage: 5V. WebThis question is about the leakage current into the ADC input channel(s) of SAR ADC's such as the ADS7844, ADS7841, ADS7828 or many other TI ADCs in this class. The datasheets provide only a "Typical" leakage current spec (usually +/- 1uA ), but do not provide "Min" and "Max" values for leakage current, or temperature drift specs.

WebThe MDC91127 is a 128-channel, 16-bit, current-input, analog-to-digital converter (ADC). It integrates current-to-voltage conversion with analog-to-digital (A/D) conversion in a single package. 128 low-level, current-output devices (e.g. photodiodes) can be directly connected to its inputs and digitized. The input range can be as low as 4pC. WebOct 26, 2024 · Equation 1, for the average input current, is based on the familiar equation for total charge in a capacitor: Qin = Cin × Vin (1) Where Qin is the total charge on the Cin and Vin is the voltage of the sampling capacitor at the end of the acquisition period, which is approximately equal to the voltage on the ADC inputs.
