1 Temperature range for the B version is −40°C to +85°C.
2 See the Terminology section.
3 This specification applies when reading during a conversion or after a conversion. If reading during a conversion in parallel mode with VDRIVE = 5 V, SNR typically reduces by 1.5 dB
and THD typically reduces by 3 dB.
4 LSB means least significant bit. With ±5 V input range, 1 LSB = 610.35 µV. With ±10 V input range, 1 LSB = 1.22 mV.
5 This specification includes the full temperature range variation and contribution from the internal reference buffer but does not include the error contribution from
the external reference.
6 Bipolar zero code error is calculated with respect to the analog input voltage.
7 Sample tested during initial release to ensure compliance.
8 Operational power/current figure includes contribution when running in oversampling mode.
