The LTC2287CUP is an analog-to-digital converter (ADC) with a unique combination of features and performance. It is designed for data acquisition and signal processing applications, such as high-speed analog-to-digital signal conversion and signal conditioning. The device offers a wide range of features and benefits to applications designers, including low power consumption, high speed sampling, high accuracy, and wide data acquisition rate.

The LTC2287CUP is based on a proprietary ADC core, the Delta-Sigma384, which incorporates a wide range of analog-to-digital conversion capabilities. This ADC architecture has been designed to achieve superior performance levels in terms of sampling rates, power consumption, and signal conditioning accuracy.

The core of the LTC2287CUP consists of an analog-to-digital conversion module and a signal conditioning module. The analog-to-digital conversion module consists of three components. The first is a 12-bit delta-sigma ADC with 128 taps, which is capable of providing up to 38.2 MHz sampling rate. The second segment consists of a high-speed single-channel multiplexer and multiple-gain stage for analog inputs up to ± 10V. The third segment houses a high-speed clock oscillator and a voltage reference.

The signal conditioning module includes a dual-channel antialiasing filter, a digital down-conversion stage and a digital error correction circuit. The digital down-conversion stage reduces the sampling rate by 2 to 256 times with up to 40 bits of resolution per channel. The digital error correction circuit provides compensation for gain and offset errors, thereby ensuring an accurate reconstructed analog output.

In addition to the high performance of its core, the LTC2287CUP also offers a wide range of software-programmable features. These include various digital down-conversion stages and antialiasing filter configurations, as well as programmable gain, offset and filter coefficients.

The LTC2287CUP is suitable for a variety of applications, including test and measurement, industrial control and instrumentation, medical imaging, telecommunications, and aerospace and defense. It is designed for use in data logging and analog signal conditioning applications, such as high-speed ADC applications, analog data acquisition systems, and other signal conditioning and processing applications.

In summary, the LTC2287CUP is an advanced, high-performance analog-to-digital converter with a range of features and benefits for a variety of applications. It offers state-of-the-art performance in terms of sampling rate, power consumption, accuracy and dynamic range, making it an excellent choice for a range of data acquisition and signal conditioning applications.
