Data acquisition is a process in which data or information is collected or measured. It involves electronic components to capture, store and transmit the data to a computer for further analysis. Analog-to-digital converters (ADCs) are a type of electronic component used to convert an analog signal into its equivalent digital representation. The LTC2453CDDB#TRMPBF is an ADC designed for board-level data acquisition. This application note examines its features, operation, application field and working principle in detail.

Features of the LTC2453CDDB#TRMPBF

The LTC2453CDDB#TRMPBF is a 24-bit, low-power, 4-channel delta-sigma ADC with a wide range of features that make it particularly suitable for board-level data acquisition. It features a wide operating temperature range (-40C to 85C) and low power consumption to ensure high reliability and accuracy even in harsh environments. Furthermore, the device offers up to 4 channels, making it suitable for high channel count systems. It also has a low noise floor, programmable gain, and wide dynamic range, making it ideal for dynamic signal environments. The combination of these features makes the device well-suited for use in automotive and industrial control applications.

Operation of the LTC2453CDDB#TRMPBF

The LTC2453CDDB#TRMPBF operates in a three-stage process, during which it converts incoming analog signals into their equivalent digital representation. In the first stage, the device uses delta-sigma modulator circuitry to convert the analog signals into a single bit signal stream. In the second stage, an extra bit is added to the signal stream to reduce noise and jitter. Finally, a 24-bit ADC is employed to convert the signal stream into digital form. The resulting digital output is then buffered, amplified and conditioned to provide a digital representation of the original analog signal.

Application Field

The LTC2453CDDB#TRMPBF is designed for board-level data acquisition applications. It is particularly well-suited for automotive and industrial control applications, due to its wide operating temperature range, low power consumption and wide dynamic range. In addition, the wide range of features makes it suitable for use in a broad range of data acquisition applications, including environmental sensing and monitoring, acceleration sensing, audio/speech processing, automotive/medical applications and more.

Working Principle

The LTC2453CDDB#TRMPBF incorporates a three-stage architecture to convert incoming analog signals into their equivalent digital representation. In the first stage, an integrated delta-sigma modulator circuit is used to convert the analog signal into a single bit digital signal stream.
