In addition, its closed loop gain of up to 62 dB V/V allows for improved accuracy, advanced low frequency response and extended dynamic range in recordings.

Working Principle

The LTC1865HMS#TRPBF is an analog-to-digital (A/D) converter that uses a successive approximation technique to convert an analog signal into a digital format. Its design includes a 16-bit successive approximation register (SAR) converter and a comparator. The internal clock of the SAR converter guides the A/D conversion process.The conversion process starts with the SAR converter comparing the analog input voltage to the voltage reference. It then adjusts the internal capacitor to move closer to the input voltage and performs additional comparisons until the internal capacitor is adjusted to the correct voltage. The SAR then stores the resulting digital value and then moves on to the next conversion.The other component in the A/D conversion process is the comparator. It is responsible for comparing the analog input voltage to the successive approximation voltage produced by the SAR. The comparator provides feedback to the SAR to correct any errors that occur during the conversion process. The comparator also acts as a buffer between the other components of the A/D converter, allowing for a faster and more accurate conversion rate.

Conclusion

The LTC1865HMS#TRPBF is a versatile analog-to-digital (A/D) converter with a high sampling rate, fast settling time, and low signal distortion. It is suitable for a wide range of applications including audio and video equipment, automotive, process control, test and measurement, medical, military, and industrial automation. Its 16-bit successive approximation register and comparator allow it to accurately and quickly convert analog signals into digital format.
