NOTES

1LSB means Least Significant Bit. With the

±2.5 V input range, one LSB is 76.3 µV.

2See Definition of Specifications section. These specifications do not include the error contribution from the external reference.

3All 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.

4Tested in parallel reading mode.

5With all digital inputs forced to OVDD or OGND respectively.

6Contact factory for extended temperature range.

Specifications subject to change without notice.

(–40 C to +85 C, AVDD = DVDD = 5 V, OVDD = 2.7 V to 5.25 V, unless otherwise noted.)
