The LTC2481CDD#PBF is an analog to digital converter falling into the category of Data Acquisition - Analog to Digital Converters (ADC). It is a 24-bit low power Sigma Delta converter, ideal for applications which require a high resolution and low noise ADC. The device is capable of sampling over a range of 0V to 2.5V and requires a power supply of 2.7V to 5.25V to operate.

The LTC2481CDD#PBF is typically used in applications where speed, power and precision are all needed. It is used for signal acquisition and signal conditioning in devices including thermocouples and RTDs, pressure sensors, signal conditioning and precision data acquisition systems. It can be used in many signal acquisition applications, including instrumentation amplifiers, thermocouples, RTDs and resistive sensors, as well as plant monitoring, signal conditioning and precision data acquisition systems.

The LTC2481CDD#PBF has a maximum sampling rate of 4096 samples per second (Sa/s). It is designed with a low power consumption of only 1.8 mW at 1.2V. The resolution is fixed at 24 bits with no missing codes; the device is monotonic over the entire input range.

The LTC2481CDD#PBF has a built-in reference and offers digital filtering and decimation, making it an ideal choice for demanding applications. Additionally, the device can be interfaced with either an SPI/QSPI or I2C interface, making it easy to integrate into a system design. The device also includes an on-board test mode and temperature sensor for additional diagnostic monitoring.

The working principle of the LTC2481CDD#PBF is based on a Integrating DELTA-Sigma Converter architecture. This architecture uses a single-bit data stream to represent the analog signal which is being converted. This stream is then integrated and clocked out of the device at a rate of 4096 S/s. Once the signal has been integrated, it is fed back to the ADC in order to form an analog-to-digital conversion.

Overall, the LTC2481CDD#PBF is an ideal solution for applications that require high resolution, low power and reliable conversions. The device is available in different configurations, allowing designers to select the best fit for their application. It is also easy to interface with existing systems, making it an ideal choice for many signal acquisition and conditioning applications.
