A TI-ADC (50) comprising a group of sub-ADCs (A1-A M+N ) is disclosed. During operation, M ≥2 of the sub-ADCs (A1-A M+N ) are simultaneously operated for converting M respective consecutive input signal samples of the TI-ADC (50) from an analog to a digital representation. The total number of sub-ADCs (A1-A M+N ) in the group is M+N, N ≥1. The TI-ADC (50) comprises error-estimation circuitry (60) for estimating errors of the sub-ADCs (A1-A M+N ). Furthermore, the TI-ADC (50) comprises a control circuit (55) configured to, for each input signal sample, assign which sub- ADC (A1-A M+N ) is to operate on that input signal sample. The control circuit (55) is configured to, for sub-ADCs (A k 1) in a first subset of the group of sub-ADCs (A1-A M+N ), which are subject to error estimation by the error-estimation circuitry (60), perform the assignment according to a first scheme. Moreover, the control circuit (55) is configured to, for sub-ADCs (A k 2) in a second subset of the group of sub-ADCs (A1-A M+N ), which are not subject to error estimation by the error-estimation circuitry (60), perform the assignment according to a second scheme, different from the first scheme.
