Data acquisition involves the conversion of a real-world signal into digital form. Analog to digital converters (ADC) are used for this purpose. One of the commonly used ADC is the LTC2265CUJ-12#PBF. This article explains the application field and working principle of the LTC2265CUJ-12#PBF.

Overview of LTC2265CUJ-12#PBF

The LTC2265CUJ-12#PBF is a low voltage, low power, 8-bit analog to digital converter (ADC). It supports a wide input voltage range from 2.7 V to 5.25 V and operates from a single 5 V supply. The power consumption of the device is typically less than 100 mW in a wide range of applications. The on-board reference voltage can be configured to provide a wide range of input resolutions, thus making it suitable for low power and low voltage applications.

The LTC2265CUJ-12#PBF is a single-ended input, single channel ADC. It comes with selectable differential or single-ended input configurations and a wide range of digital output configurations. The device has an on-chip 12-bit digital filter along with a digital gain error correction feature. This enables it to achieve up to 8-bit resolution with very low noise and distortion. The device can also be used in differential mode to achieve even better noise immunity and accuracy.

Application of LTC2265CUJ-12#PBF

The LTC2265CUJ-12#PBF is an ideal choice for use in low voltage and low power applications. It is typically used in medical, industrial, and automotive applications. The device can also be used for data acquisition, measuring signals in broadcasting, audio, and electric motor control systems. Due to its low power consumption the device can be used in portable and battery powered systems. The on-board reference voltage can be configured to provide a low input resolution which is suitable for portable applications. Furthermore, the digital filter, digital gain error correction and differential inputs allows the device to have very low noise and very high accuracy.

Working Principle of LTC2265CUJ-12#PBF

At the core of the LTC2265CUJ-12#PBF is a 8-bit successive approximation register (SAR). The SAR consists of a digital-to-analog converter (DAC), comparators, and a latch. The device samples the analog input at a predetermined clock rate and uses the SAR to convert the analog input into a digital output. The device also contains a digital filter that can be configured to perform data filtering and error correction. This allows the converter to produce an accurate and low noise output.

The on-chip reference voltage can be programmed to provide a wide range of input resolutions. This enables the converter to achieve very low noise and distortion over a wide range of input voltage ranges. The device can also be used in differential mode to further reduce the noise and improve the accuracy of the converter. The output of the ADC is formatted into a digital format as per the user\'s requirement.

Conclusion

The LTC2265CUJ-12#PBF is a 8-bit analog to digital converter (ADC) that is designed for low power and low voltage applications. The device has an on-chip 12-bit digital filter along with a digital gain error correction feature that enables it to achieve up to 8-bit resolution. It is commonly used in medical, industrial, and automotive applications for data acquisition, measuring signals in broadcasting, audio, and electric motor control systems. The on-chip reference voltage can be configured to provide a wide range of resolutions and the outputs can be formatted in a variety of digital formats.
