Mwave ™ is a trademark of the IBM Corporation. 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 (>1M Ω) 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. CS4215 2 DS76F2 |
