12-bit 2MS/s Dual Input ADC with Temperature Sensor
The S3ADTS2M12BC18 is a low-power, dual input, reconfigurable 12/10-bit ADC IP that includes a temperature sensor core. The S3ADTS2M12BC18 corresponds to the S3AD2M12BC18 with the addition of a temperature sensor core. For details on the ADC operation when using any of the external inputs, please refer to the S3AD2M12BC18 datasheet v2.9 from Dec. 2009.
In the present datasheet we provide details on the digital temperature sensor functionality only.
When the temperature sensor mode is active, the ADC digitizes the T-sensor analog output in 12-bit mode at 1.7MS/s.
Digital controls RESET, CLKEN, CLK and EOC are operated exactly as for the S3AD2M12BC18.
