If reading during a conversion in parallel and serial modes with VDRIVE = 5 V, SNR typically reduces by 1.5 dB and THD by 3 dB. 4 LSB means least significant bit. With ±5 V input range, 1 LSB = 76.29 µV. With ±10 V input range, 1 LSB = 152.58 µV. 5 These specifications include the full temperature range variation and contribution from the internal reference buffer but do not include the error contribution from the external reference. 6 Bipolar zero code error is calculated with respect to the analog input voltage. See the Analog Input Clamp Protection section. 7 Sample tested during initial release to ensure compliance. 8 Operational power/current figure includes contribution when running in oversampling mode.
