The LTC2173CUKG-12#PBF is an Analog-to-Digital Converter (ADC) with a 12-bit resolution and a maximum conversion rate of 3Msps. It features a differential or single-ended input mode, as well as a calibration logic that allows users to fine-tune the accuracy of their applications. It also features an enhanced sampling system that performs two consecutive fast-trace holds for reduction of clock jitter and timing errors.

The device comes with an advanced 12-bit successive approximation register (SAR) architecture that offers high precision and noise immunity. Furthermore, a high input impedance also allows the device to measure highly accurate signals. The device has a 52dB signal-to-noise ratio (SNR) that makes it a great choice for applications such as medical imaging, automotive, and industrial test and measurement.

The LTC2173CUKG-12#PBF is specifically designed for applications where two channels are needed for high-resolution and low-noise performance. It has a power supply range of 3.3V and 5V, which allows for reliable operation over a wide temperature range. The device has a high speed serial interface (SPI/QSPI) and an 8-bit digital output, which allows for easy data acquisition.

The LTC2173CUKG-12#PBF uses the successive approximation register (SAR) architecture to convert analog signals into digital signals. In SAR, the analog signal is compared with a reference voltage that is generated by a digital-to-analog converter (DAC). After each comparison, the comparison results are used to update the DAC reference voltage a bit at a time until the analog signal is within the desired accuracy. The device uses a high capacity memory that is mapped simultaneously to achieve high speed conversion. It also includes a clock cycle splitting technique to divide the clock cycle into two parts of adjacent clocks to eliminate jitter and timing errors.

The LTC2173CUKG-12#PBF also provides an on-chip gain calibration option for improved accuracy. The calibration logic allows users to adjust the output full-scale range, gain scale factor, and system gain in order to fine-tune the accuracy of their applications. It also features a continuous single-channel conversion that converts a new sample every cycle, providing a maximum throughput that is greater than 1Msps.

In summary, the LTC2173CUKG-12#PBF is an excellent choice for applications that require high-resolution, low-noise performance. Its advanced SAR architecture and integrated calibration function enhance accuracy and reduce system noise to provide a reliable and accurate data acquisition solution. Its wide input voltage range and fast throughput rate make it a great choice for applications such as medical imaging, automotive, and industrial test and measurement.
