External crystal or internal OSC ON
1 All ADC channel specifications are guaranteed during normal MicroConverter core operation.
2 Apply to all ADC input channels.
3 Not production tested; supported by design and/or characterization of data on production release.
4 Measured using an external AD845 op amp as an input buffer stage, as shown in Figure 42. Based on external ADC system components.
5 The input signal can be centered on any dc common-mode voltage (VCM), as long as this value is within the ADC voltage input range specified.
6 When using an external reference input pin, the internal reference must be disabled by setting the LSB in the REFCON memory mapped register to 0.
7 Endurance is qualified as per JEDEC Std. 22 Method A117 and measured at 40°C, +25°C, and +85°C.
8 Retention lifetime equivalent at junction temperature (TJ) = 85°C as per JEDEC Std. 22 Method A117. Retention lifetime derates with junction temperature.
9 Test carried out with a maximum of eight I/Os set to a low output level.
10 Power supply current consumption is measured in normal, pause, and sleep modes under the following conditions: normal mode = 3.6 V supply, pause mode = 3.6 V
supply, sleep mode = 3.6 V supply.
11 IOVDD power supply current decreases typically by 2 mA during a Flash/EE erase cycle.
