Data acquisition, which covers the process of obtaining signals from the real world, is a critical component of the overall operation of many scientific and industrial systems. Among different data acquisition systems, analog to digital converters (ADC) are essential for capturing and converting analog signals into digital form. The LTC2433-1CMS#TRPBF is a low-power, 24-bit, serial-input analog-to-digital converter designed for measuring ±10V input signals. In this article, we will discuss the application field and working principle of the LTC2433-1CMS#TRPBF.

Application Field

The LTC2433-1CMS#TRPBF is a high-accuracy, low-power ADC that is suitable for many industrial and laboratory applications, including measurements of current, pressure, force, temperature and voltage. Additionally, it can be used in consumer products such as weight scales and medical equipment. With its 24-bit resolution, the LTC2433-1CMS#TRPBF is capable of capturing high-fidelity signals with minimal noise and distortion. The low power consumption of the device allows it to be used in battery-powered systems.

Working Principle

The LTC2433-1CMS#TRPBF utilizes a Delta-Sigma topology with no missing codes, making it ideal for measuring 16-bit resolution signals with up to 24 bits of effective resolution. The device has a single 5V analog supply voltage, consisting of a 3.3V internal reference, a 0.3V preamplifier, and a 1.2V programmable gain amplifier (PGA). The PGA also provides low-pass filtering of the analog signal before conversion, resulting in improved signal-to-noise ratio.

In operation, the analog signal is first amplified and filtered by the PGA before being sampled and converted by the Delta-Sigma modulator. The Delta-Sigma modulator then converts the analog signal into a 24-bit digital output code. The output code can be formatted in either straight binary (BIN) or two’s complement (TC). The 24-bit resolution is typically achieved with internal oversampling, allowing for low distortion and high precision.

Conclusion

The LTC2433-1CMS#TRPBF is a high-resolution, low-power ADC with 24-bit resolution and excellent dynamic range. Its Delta-Sigma modulator and programmable gain amplifier ensure that the device can accurately convert 16-bit resolution signals with minimal noise and distortion. Additionally, its low power characteristics make it ideal for battery-powered systems. Overall, the LTC2433-1CMS#TRPBF offers a robust solution for many data acquisition applications across many industrial and laboratory fields.
