Data Acquisition is the process of responding and collecting data from different sources. A Digital-to-Analogue Converter (ADC) is one of the more common types of device used in this context, as it takes a wide range of analog signals, such as temperature, pressure, and light, and converts them into digital data. One of the more popular ADCs on the market is the LTC2232IUK#TRPBF. It is a high performance, dual channel 12 bit, low power, very fast analog-to-digital converter.

Features and Benefits

The LTC2232IUK#TRPBF looks to provide accurate data acquisition with its 12 bit resolution. It also has a 2.5V internal reference for measurements between 0V to 2.5V and is capable of a maximum frequency of 500 KSPS. The device’s flexible architecture allows for use in both single-ended and differential input configurations. This can be even further tailored to a user’s needs, with the addition of external components to tailor input range, power consumption, and other characteristics. The device also has an active-low shutdown pin to conserve power as well as an available output data rate of 5K SPS. The power consumption of the device is quite low, with a typical value of 25mW at 5k SPS.

Application Fields

The LTC2232IUK#TRPBF is suitable to measure a wide range of signals, including pressure transducers, strain gauges, and thermocouples. It is also well suited to a variety of applications, including industrial, data acquisition, automotive, avionics, and robotics. Its low power consumption makes it ideal for battery powered devices, as well as its fast max frequency for a timely conversion between input and output data. These features make it a versatile and popular choice for many applications.

Working Principle

The LTC2232IUK#TRPBF ADC processes the analog signal and converts it into digital form. This data is then outputted via the serial I/O protocol. It uses successive approximation techniques to internally convert the analog signal into a digital form. This involves comparing the analog input signal to a reference voltage, such as 2.5V, and using a series of progressively more accurate comparisons to determine each bit of the digital output. The ADC will then output the resulting 12 bits of digital data, which is then able to be further processed by further circuits.

Conclusion

The LTC2232IUK#TRPBF is a compact, low power, high performance, dual channel 12 bit analog-to-digital converter. It is a popular choice due to its flexibility, low consumption and accurate data conversion. It has a wide range of applications, mainly in industrial, data acquisition, automotive, avionics and robotics due to its ability to convert analog to digital quickly and with a high degree of accuracy.
