Notes: 1. This specification is guaranteed by characterization, not production testing.
2. Very low frequency signals will be slightly distorted when using the HPF.
3. Input resistance is for the input selected. Non-selected inputs have a very high (>1MΩ) input
resistance.
4. DC current only. If dynamic loading exists, then CMOUT must be buffered or the performance of
ADC’s and DAC’s may be degraded.
