Data Acquisition - Analog to Digital Converters (ADCs) play an important role in modern technology, providing precise measurements of analog signals in digital form. A data acquisition system with an ADC allows engineers to acquire data quickly, transfer it to a processor, and process it. Among these data acquisition-based systems is the LTC2378CMS-16#TRPBF, which boasts best-in-class performance and powerful features.

The LTC2378CMS-16#TRPBF is a 16-bit, parallel interface, low power, high speed, low noise, differential input SAR (successive approximation register) ADC. It has an input range of ±2.5V, with a single cycle settling time of 53ns and a conversion rate of up to 250 kSps. With a peak signal-to-noise ratio (SFDR) of 123dB across the audio bandwidth, it’s ideal for high-fidelity audio applications.

The LTC2378CMS-16#TRPBF also features an innovative input sampling capacitor array, which significantly reduces its input power consumption. This makes it well suited for portable applications, such as portable medical devices, test instruments, and consumer electronics.

The LTC2378CMS-16#TRPBF’s 3-wire interface is easy to connect, and its 10MHz reference clock allows it to sample input signals quickly and accurately. It also includes a Serial Peripheral Interface (SPI) for easy programming, and an integrated digital filter for signal conditioning. This makes it suitable for a wide range of applications, from consumer audio and video, to lab, industrial and automotive systems.

At the core of the LTC2378CMS-16#TRPBF is its powerful SAR-based conversion architecture. The signal-to-noise ratio (SNR) and signal-to-noise-and-distortion ratio (SINAD) performance of the device is outstanding, with a maximum SNR of 105dB and SINAD of 81dB. The device features a high data rate of up to 250 kSps and can be configured by SPI to sample at a data rate of up to 800 kSps. The conversion process in SAR architecture starts with the input signal being sampled and held by the sampling capacitors. Then the successive approximations register test each bit value and decides upon the final output code by comparing it with the internal reference voltage. This process is repeated until the output code converges to the same value.

In summary, the LTC2378CMS-16#TRPBF is an ideal data acquisition system for high-resolution, low power and high-speed applications. Its range of features, low power and quick conversion rate make it suitable for a variety of applications, and its outstanding SFDR and SNR combined with its fast settling ensure accurate, high-fidelity measurements. This ADC also brings digital signal conditioning capabilities to the table, which makes it an all-in-one solution for many high-performance data acquisition systems.
