ST62T35B/E35B
6.2 RECOMMENDED OPERATING CONDITIONS
Notes:
1. Care must be taken in case of negative current injection, where adapted impedance must be respected on analog sources to not affect
the A/D conversion. For a -1mA injection, a maximum 10 K
2. An oscillator frequency above 1MHz is recommended for reliable A/D results.
