All ADC Channel Specifications are guaranteed during normal MicroConverter core operation.
These specification apply to all ADC input channels.
These numbers are not production tested but are supported by design and/or characterization data on production release.
Based on external ADC system components, the user may need to execute a system calibration to remove external endpoint and achieve these specifications..
SNR calculation includes distortion and noise components.
Channel-to-channel crosstalk is measured on adjacent channels.
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 Memeory Mapped Register to 0.
Endurance is qualified to 50,000 cycles as per JEDEC Std. 22 method A117 and measured at -40°C, +25°C and +85°C. Typical endurance at 25°C is 70,000 cycles.
Retention lifetime equivalent at junction temperature (Tj) = 55°C as per JEDEC Std. 22 method A117. Retention lifetime will derate with junction temperature.
Test carried out with a maximum of 20 I/O set to a low output level.
Power supply current consumption is measured in normal, idle and power-down modes under the following conditions:
