These videos describe how to design the input driver circuitry for a successive approximation register analog-to-digital converter (SAR ADC).
The goal of this section is to cover reference specifications, gain a deeper understanding of the SAR voltage reference behavior, and develop methods for driving the reference input that minimize error.
These videos describe how to design a low-power data acquisition system using a successive approximation register analog-to-digital converter (SAR ADC).
PT100/500/1000 Resistance Temperature Detectors (RTDs) are widely used in grid infrastructure and factory automation applications where high precision temperature measurement is often required. Technical requirements include either 20 mK precise Differential Temperature Measurement (DTM) for heat and cold meters from 0 to 180°C or better than 400 mK precision over the full range of -200 to 850°C for industrial sensor transmitters.
The TMP116 digital precision temperature sensor for the -55 to +125ºC range achieves higher accuracy than the Class AA PT sensor with a 1-point calibration. A small PCB including TI's TPD1E10B06 or TPD1E04U04 protection devices can be sealed into a RTD metal tube and meet the EN 61000-4-2 and -4-4 levels of ESD protection. The 64-bit internal EEPROM inside TMP116 stores user defined calibration data into the digital temperature sensor, simplifying integration with application MCUs, such as MSP430FR6047, FR6989 or CC13xx/26xx wireless MCU families.
From simplifying high voltage current measurements to getting the most out of a SAR ADC, these data converter training videos explore everything from selecting the right DAC to defining a multiplying DAC.
