Analog Devices Inc. LTC2402CMS#TRPBF - 24-Bit No Latency Delta Sigma ADC

The LTC2402CMS#TRPBF from Analog Devices Inc. is a high-precision 24-bit No Latency Delta Sigma™ Analog-to-Digital Converter (ADC) that offers a compelling solution for advanced data acquisition systems requiring high resolution and accuracy. It is part of the LTC2402 series, designed to meet the rigorous demands of industrial, automotive, and instrumentation applications.

This ADC features a differential input and an integrated oscillator, simplifying the design process by reducing the number of external components required. The LTC2402CMS#TRPBF operates from a single 2.7V to 5.5V power supply and provides a full-scale input range of ±Vref, with Vref ranging from 0.1V to Vcc. This allows for a flexible reference selection to match the required input signal amplitude, optimizing the dynamic range for various applications.

The device boasts an impressive sampling rate of 10 samples per second, providing a perfect balance between speed and power consumption. This makes it suitable for battery-powered and remote sensing applications where power efficiency is crucial. The LTC2402CMS#TRPBF also features a No Latency Delta Sigma architecture, which eliminates the pipeline delay found in conventional delta sigma converters, ensuring single-cycle settling time for multiplexed applications.

Communication with the LTC2402CMS#TRPBF is straightforward, as it uses a simple 3-wire SPI-compatible serial interface. This interface is compatible with several microcontrollers and digital systems, making it easy to integrate into existing designs. The device is offered in a compact 10-lead MSOP package, which is ideal for space-constrained applications.

The LTC2402CMS#TRPBF incorporates multiple built-in features such as a selectable internal/external reference and a proprietary input overvoltage protection, which shields the ADC from damage up to ±25V, far beyond the supply rails. This robustness makes it an excellent choice for harsh environments where input signals may be unpredictable.

In summary, the LTC2402CMS#TRPBF by Analog Devices Inc. is a versatile and reliable ADC that delivers high-precision measurements, low power consumption, and ease of use, making it a top choice for engineers and designers working on sophisticated electronic systems.
