1
All ADC channel specifications are guaranteed during normal MicroConverter core operation.
2
Apply to all ADC input channels.
3
Measured using the factory-set default values in the ADC offset register (ADCOF) and gain coefficient register (ADCGN).
4
Not production tested but supported by design and/or characterization data on production release.
5
Measured using the factory-set default values in ADCOF and ADCGN with an external AD845 op amp as an input buffer stage as shown in Figure 59. Based on external ADC
system components; the user may need to execute a system calibration to remove external endpoint errors and achieve these specifications (see the Calibration section).
6
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.
7
DAC linearity is calculated using a reduced code range of 100 to 3995.
8
DAC gain error is calculated using a reduced code range of 100 to internal 2.5 V VREF.
9
Endurance is qualified as per JEDEC Standard 22, Method A117 and measured at 40°C, +25°C, +85°C, and +125°C.
10
Retention lifetime equivalent at junction temperature (TJ) = 85°C as per JEDEC Standard 22m, Method A117. Retention lifetime derates with junction temperature.
11
Test carried out with a maximum of eight I/Os set to a low output level.
12
See the POWCON register.
13
Power supply current consumption is measured in normal, pause, and sleep modes under the following conditions: normal mode with 3.6 V supply, pause mode with
3.6 V supply, and sleep mode with 3.6 V supply.
14
IOVDD power supply current decreases typically by 2 mA during a Flash/EE erase cycle.
15
On the ADuC7019/20/21/22, this current must be added to the AVDD current.
