2.2 RECOMMENDED OPERATING CONDITIONS
Notes
:
1. Care mustbe taken in case of negative current injection, where adapted impedance must be respected on analog sources tonot affect the
A/D conversion. For a -1mA injection, a maximum 10 K
is recommended.
2.An oscillator frequency above 1MHz is recommended for reliable A/D results
