Analog-to-Digital Converters (ADCs) are devices which convert a continuous analog signal into a digital representation of that signal. The LTC1282ACSW#TRPBF is a 2-channel precision low noise amplifier-sampling Analog-to-Digital Converter (ADC) designed for use in applications such as waveform capture, instrumentation and data acquisition. It is available in both 16 and 24-bit versions, offering precision performance and excellent dynamic range. This article will detail the application field and working principle of the LTC1282ACSW#TRPBF.

Application Field

The LTC1282ACSW#TRPBF is suitable for a range of data acquisition applications, from general-purpose analog signal acquisition to high-precision analog-to-digital conversion. Its low noise architecture and low power consumption make it ideal for applications such as instrumentation, process control, biomedical systems, industrial and consumer instrumentation, automotive applications, and medical monitoring systems. The ADC features an extended input range of ±2.5 V and offers a high resolution of 16 or 24 bits.

Working Principle

The LTC1282ACSW#TRPBF is based on a single-ended track-and-hold circuit that samples, differentiates, and amplifies incoming signals. The analog input is buffered and single-ended, allowing for maximum flexibility in analog sources. The differentiator amplifies the signal and converts it into a ramp-like waveform, which is then amplified by the track-and-hold circuit. The sampled input is then fed into a successive approximation register with 16 or 24-bit resolution. The results of the conversion are latched into the output register, which is then output as the digital value of the analog input.

The ADC includes various safety measures, such as power-on reset and thermal shutdown, to guard against noise and fault conditions. There is also a built-in peak-detection circuit, which measures the peak value of the input signal and stores it in a register. This allows the ADC to store an accurate snapshot of the input signal, which can be later retrieved and used for further analysis.

The LTC1282ACSW#TRPBF is a high-precision, low-power, low-noise ADC designed for a range of data acquisition applications. Its extended input range and 16 or 24-bit resolution make it ideal for a wide range of applications. Its sample and hold, tracks and differentiates, and successive approximation registers provide precision performance and excellent dynamic range. The LTC1282ACSW#TRPBF also offers a peak-detection circuit, which allows the ADC to store an accurate snapshot of the input signal. The LTC1282ACSW#TRPBF is an excellent choice for a variety of data acquisition needs.
