Data Acquisition - Analog to Digital Converters (ADC) has recently seen a tremendous growth in the industry, with the LTC1272-5ACN#PBF being the latest and greatest addition to the family. A part of the Linear Technology\'s family of low-cost, low-power analog-to-digital converters, the LTC1272-5ACN#PBF is designed for integrating 12-bit data acquisition systems. The key features of the LTC1272-5ACN#PBF include 12-bit Resolution, Sample & Conversion Rate of 125Ksps (25ksps true single cycle conversion), input range up to ±10V, 1 μA @ 3V supply current, and ±0.02% linearity in voltage. These features make the LTC1272-5ACN#PBF suitable for various applications such as industrial, consumer/professional, medical/industrial instrumentation, aerospace, telecommunications, etc.With its high accuracy, wide input range, and small size, the LTC1272-5ACN#PBF is a great choice for use in data acquisition systems. Its low power consumption and small package size allow it to be used in small or portable applications where the environment has high noise levels or requires long-term stability. Its low-speed conversion rate makes it ideal for low-throughput data acquisition tasks. The LTC1272-5ACN#PBF uses a four-channel, 3-order filter, which is selectable by a serial interface. With the help of an internal track/hold, this filter helps to reduce the noise typically seen in other data converters. It also supports differential, pseudo-differential, and single-ended input modes. The working principle of the LTC1272-5ACN#PBF is based on the switching method of analog-to-digital conversion. It takes the analog voltage input signal, multiplexes it over four channels, and then converts it into a coded output signal. The multiplexer consists of two differential comparators, followed by a signal amplifier and an analog-to-digital converter. The analog input signal is converted into a digital signal (by compressing and expanding the range) before it passes through the filter. After the filter, a series of digital calculations are made to quantize the signal into 24 bits and then a 12-bit offset-corrected digital signal is provided as an output.The LTC1272-5ACN#PBF\'s high precision and wide input range gives it an edge in performance compared to other ADC devices when it comes to data acquisition. Its low power consumption and small package size also make it an attractive solution for use in portable or embedded applications. With its competitive pricing and wide range of features, it is easy to see why the LTC1272-5ACN#PBF is a popular choice for data acquisition.
