Specifications subject to change without notice.
LSB means Least Significant Bit. With the 0 V to 2.5 V input range, one LSB is 38.15 µV.
See Definition of Specifications section. These specifications do not include the error contribution from the external reference.
Tested in warp mode.
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.
In warp mode.
Tested in parallel reading mode.
In impulse mode.
With all digital inputs forced to OVDD or OGND respectively.
Contact factory for extended temperature range.
