Data Acquisition - Analog to Digital Converters (ADC)

LTC2451CDDB#TRPBF Application Field and Working Principle

The LTC2451CDDB#TRPBF is a low-power, ultra-high-resolution monolithic sampling analog-to-digital converter (ADC) of Texas Instruments (TI). It provides excellent performance for data acquisition and signal conditioning applications. The ADC provides an excellent combination of industry-leading resolution, low noise, and low-power for a wide variety of analog input signal types.The LTC2451CDDB#TRPBF is a single-channel, 16-bit ADC with a total of 17-bit effective resolution. It is a single-ended input with an input voltage range from ground to the supply voltage (VCC). It utilizes a single-slope conversion with a built-in programmable filter option. The filter option offers the additional flexibility of filtering off any frequency components above a given cut-off frequency. The ADC can operate on a 2.7V to 5.5V single supply, and with an integrated 0.75µA shutdown mode, you can reduce the power consumption even further. It also features a two-wire serial interface which allows for both calibration and operation with compatible microcontrollers and FPGAs. The user can also choose between two operating speeds, fast or slow, to further optimize the performance, power consumption and area savings.The LTC2451CDDB#TRPBF has a wide range of applications, including power monitoring, medical instrumentation, data collection, process measurement, and other embedded devices. The ADC provides very high precision and low noise performance, making it highly suitable for wide variety of industrial and consumer applications. Additionally, it has low-power performance at low sample rates, allowing it to be used in battery-powered applications.In terms of its working principle, the LTC2451CDDB#TRPBF is based on a single-slope conversion technique. It operates with a differential voltage input, and one input terminal is connected to the reference voltage terminal. The analog input is applied to the other terminal and is then converted into a digital output. The output is then acquired and can be used to perform calculations or display results on a display. The LTC2451CDDB#TRPBF utilizes a high-precision delta-sigma modulator which processes the input signal and produces a high-resolution output. A low-pass filter is implemented before the modulator to reduce noise and eliminate aliasing.In summary, the LTC2451CDDB#TRPBF is an excellent choice for high-precision, low-noise and low-power analog to digital conversion. With its wide input voltage range, high resolution, and ultra-low-power performance, it makes a great choice for embedded devices, power monitoring, and medical instrumentation. The single-slope conversion and the integrated filter provide additional flexibility and performance, making it suitable for a wide variety of applications.
