NOTES
1LSB means Least Significant Bit. With the 0 V to 2.5 V input range, one LSB is 38.15
V.
2See Definition of Specifications section. These specifications do not include the error contribution from the external reference.
3Tested in warp mode.
4All 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.
5In warp mode.
6Tested in parallel reading mode.
7In impulse mode.
8With all digital inputs forced to OVDD or OGND respectively.
9Contact 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.)
