The circuit arrangement (10) for monitoring a battery cell is designed to receive a first measurement signal which is representative of a cell voltage of the battery cell. The first measurement signal is supplied to a main monitoring channel (20) of the circuit arrangement (10), the main monitoring channel comprising a first analog-to-digital converter (ADC) (24), and to a redundant monitoring channel (30) of the circuit arrangement (10), the redundant monitoring channel comprising a second ADC (34). A reference signal is determined depending on the first output signal (U_MAIN) of the main monitoring channel (20) and the second output signal (U_AUX) of the redundant monitoring channel (30). If the first output signal (U_MAIN) falls below a specified first voltage value and exceeds a specified second voltage value, the reference signal is compared with a specified first trigger threshold (TH1). However, if the first output signal (U_MAIN) is equal to or greater than the specified first voltage value or is equal to or less than the second specified voltage value, the reference signal is compared with a second specified trigger threshold (TH2).
