The ICL7109CQH+TD is a Analog to Digital Converter (ADC) used in Data Acquisition applications that combines both voltage and temperature measurement capabilities. The ICL7109CQH+TD integrates two powerful devices into a single integrated circuit. On the one hand, there is a precision, low cost and highly accurate 12-bit, successive approximation, voltage-input analog-to-digital (ADC) converter; on the other, there is a highly integrated RTD temperature measurement circuit with a built-in thermocouple amplifier. It supports a wide range of input currents ranging from -1A to +1A. The output resolution is +/- 3mA. The PWM resolution is 8 bits.

When the ICL7109CQH+TD is used in data acquisition applications the input voltage is measured with the ADC and the temperature is measured by the RTD temperature circuit using the thermocouple amplifier. The voltage-input ADC has a wide input range from ±70V and its exact value is encoded into a 9-bit register. The RTD temperature circuit incorporates an onboard amplifier which amplifies the temperature signal from the RTD and converts it into an 8-bit digital value. Both outputs are available at the same time.

The ICL7109CQH+TD is well suited for low-speed data acquisition applications such as remote monitoring, control and test equipment, automotive systems, and industrial control and automation applications. It is also suitable for high-speed data acquisition applications such as in crosstalk measurements, power quality monitoring, analog-to-digital conversion, digital-to-analog conversion, and pulse-width modulation control.

The working principle of the ICL7109CQH+TD is quite simple. The device is configured to measure the input voltage using its onboard analog-to-digital converter and its onboard temperature measurement circuit. It then processes the incoming data and converts it into a digital format. The output of the device is then fed to a data acquisition system, which can then be used to analyze and monitor the performance of the device.

Overall, the ICL7109CQH+TD is an excellent choice for data acquisition applications requiring low-power and high accuracy. It provides a reliable and efficient way of capturing and measuring data. Its versatility and range of supported input currents make it an ideal choice for a wide range of applications.
