Temperature range for the B version is −40°C to +85°C.
See the Terminology section.
This specification applies when reading during a conversion or after a conversion. If reading during a conversion in parallel mode with V
and THD typically reduces by 3 dB.
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.
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.
Bipolar zero code error is calculated with respect to the analog input voltage.
Sample tested during initial release to ensure compliance.
Operational power/current figure includes contribution when running in oversampling mode.
