Data Acquisition - Analog to Digital Converters (ADC\'s) are a key component to creating digital signals and working with our analogue world. The LTC2385IUH-16#PBF, made by Linear Technology, is an ultra-high speed, high accuracy, 16-bit, 3.1μs, dual channel synchronous successive approximation register (SAR) Analog-to-Digital Converter (ADC). In this article, we will outline the application field and working principle of the LTC2385IUH-16#PBF.

The main applications for the LTC2385IUH-16#PBF include Signal Acquisition, Instrumentation, and Data Conversion. Its capability to integrate two parallel channels with independent timing, numerous triggering modes and clock configurations, makes the ADC capable of dealing with large data-rates, even when operated with a single-ended input voltage. Furthermore, features like Over-Voltage Protection, differential-mode range extension and Data Pattern Test help in validating and transmitting data securely. This ADC also works well in conjunction with data bus applications like SPI, I2C, Serial UART and so on.

In regards to its working principles, the LTC2385IUH-16#PBF implements the SAR architecture. The SAR architecture is known to produce quantized approximations of the input signal by employing the operational amplifier and comparator that compare the input voltage to the generated reference voltage. Then, the output signals are sent to a voltage ladder which leads to the successive approximation register (SAR). The SAR then begins updating the reference voltage dependent on the digitized output and does this in a successive manner until the value it matches the required conversion ratio. This process continues for as long as needed until the ADC produces the final result. Furthermore, the ADC achieves a very fast conversion rate by running the comparator, the SAR and the reference node on the same clock source.

The LTC2385IUH-16#PBF is an excellent choice for those looking to convert analogue signals with high speed and accuracy. Its capability to function in various data conversion scenarios and its efficiency in working with the SAR architecture makes it an ideal product for any application that requires fast and secure data acquisition.
