All ADC channel specifications are guaranteed during normal MicroConverter core operation.
Apply to all ADC input channels.
Measured using the factory set default values in ADCOF and ADCGN.
Not production tested but supported by design and/or characterization data on production release.
Measured using the factory set default values in ADCOF and ADCGN using an external AD845 op amp as an input buffer stage as shown in Figure 47. 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).
The input signal can be centered on any dc common-mode voltage (V
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.
DAC linearity is calculated using a reduced code range of 100 to 3995.
DAC gain error is calculated using a reduced code range of 100 to internal 2.5 V V
supply, Sleep Mode: 3.6 V supply.
Endurance is qualified as per JEDEC Standard 22 method A117 and measured at −40°C, +25°C, +85°C, and +125°C.
Retention lifetime equivalent at junction temperature (T
Test carried out with a maximum of eight I/O set to a low output level.
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
