16 / 23 page ![]() M34E02 16/23 DC AND AC PARAMETERS This section summarizes the operating and mea- surement conditions, and the DC and AC charac- teristics of the device. The parameters in the DC and AC Characteristic tables that follow are de- rived from tests performed under the Measure- ment Conditions summarized in the relevant tables. Designers should check that the operating conditions in their circuit match the measurement conditions when relying on the quoted parame- ters. Table 8. Operating Conditions Table 9. AC Measurement Conditions Figure 12. AC Measurement I/O Waveform Table 10. Input Parameters Note: 1. TA = 25 °C, f = 400 kHz 2. Sampled only, not 100% tested. Symbol Parameter Min. Max.
