1
Operating temperature range is −40°C to +85°C (B: Version).
2
Typical values for SNR apply for parts soldered directly to the PCB ground plane.
3
Dynamic specifications apply for input signal frequencies from dc to 0.0240 × f
CLKIN
in decimate by 16 mode and from dc to 0.0120 × f
CLKIN
in decimate by 32 mode.
4
When using the internal reference, THD and SFDR specifications apply only to input signals above 10 kHz with a 10 µF decoupling capacitor between REF2 and
AGND2. At frequencies below 10 kHz, THD degrades to 84 dB and SFDR degrades to 86 dB.
5
Gain error excludes reference error.
