Data acquisition is used for measuring and recording data for a variety of tasks. There are many different types of devices used for this purpose, and among the most popular is the Analog to Digital Converter (ADC). In this article, we will focus on LTC2452CDDB#TRMPBF and explain its application field and working principle.

LTC2452CDDB#TRMPBF is a low cost 8-channel, 24-bit analog-to-digital converter (ADC) with a +/- 10V input range, 0.005% INL accuracy, and 1.5 μs throughput. It features a temperature sensor, differential inputs, fast settling, and wide supply range. This ADC is suitable for a variety of applications including industrial, military, and automotive systems.

The application field of LTC2452CDDB#TRMPBF is broad and includes applications such as factory automation, instrumentation, process control, automotive, and float-cell liquid level measurement.

The basic principle of operation of the LTC2452CDDB#TRMPBF is to digitize an analog signal, convert it to a digital representation, and then output a digital number representing the original analog signal. The device utilizes an efficient SAR architecture that allows fast sampling of the inputs while maintaining an accurate and clean digital representation.

The LTC2452CDDB#TRMPBF can be used in both single-ended and differential measurements. The differential input range of the ADC is +/- 10V. The device has two gains- a standard gain of (+/- 8V) and a high gain of (+/- 4V). Its power supply range is from 5V to 18V. The ADC also has a temperature-sensing diode for monitoring temperature.

In operation, the LTC2452CDDB#TRMPBF converts the differential input voltage to a digital value using an 8-bit power-of-two successive approximation (SAR) architecture. This architecture allows for fast conversion times, typically between 1.5 μs to 4 μs, depending on the gain setting. The device also employs an innovative irregularly spaced array interpolation technique which helps to reduce the ADC\'s integral non-linearity (INL) to 0.005%.

The LTC2452CDDB#TRMPBF has a low power consumption of typically just 73 μA and a shutdown mode that reduces the power consumption to only 25 μA. An onboard charge-pump regulator is used to power the ADC, eliminating the need for an external reference voltage.

In summary, LTC2452CDDB#TRMPBF is an ideal low cost 8-channel 24-bit ADC, suitable for a variety of applications including factory automation, instrumentation, process control, automotive and float-cell liquid level measurement. The device has an 8-bit SAR architecture, which allows fast sampling of the inputs while still providing accurate and clean digital representations. The onboard charge-pump regulator is used for power and time savings, and the device has low power consumption and a shutdown mode for additional power savings.
