If reading during a conversion in paral el mode with VDRIVE = 5 V, SNR typical y reduces by 1.5 dB and THD by 3 dB. 3 LSB means least significant bit. With ±5 V input range, 1 LSB = 152.58 µV. With ±10 V input range, 1 LSB = 305.175 µV. 4 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. 5 Bipolar zero code error is calculated with respect to the analog input voltage. 6 Sample tested during initial release to ensure compliance. 7 Operational power and current figure includes contribution when running in oversampling mode.
