NOTES
1
LSB means Least Significant Bit. With the
±
2.5 V input range, one LSB is 76.3
μ
V.
2
See Definition of Specifications section. These specifications do not include the error contribution from the external reference.
3
All specifications in dB are referred to a full-scale input FS. Tested with an input signal at 0.5 dB below full-scale unless otherwise specified.
4
Tested in parallel reading mode.
5
With all digital inputs forced to OVDD or OGND, respectively.
6
Contact factory for extended temperature range.
Specifications subject to change without notice.
