> Analog/ Digital Converter balanced input | ADC1_IN_P ADC1_IN_N |  | Single ended or differential input voltage ADCx_IN_N = GND or negative voltage ADCx_IN_P = positive voltage VI min = 0V VI max = 5V Ri single ended ≈ 600kOhm Ri balanced ≈ 1200kOhm Cut-off-frequency, fg = 70Hz Common-mode rejection ratio, CMRR > 50dB Accuracy ±1mV Accuracy total ±4mV Resolution: 2400 steps (1 step 2.083mV) Linear error ±1mV Temperature error ±1mV Burst error ±1mV | ADC1_IN and ADC2_IN are balanced lines and multiplexed with an analog switch. Both inputs are filtered by a low pass
