Overview
The LTC2143CUP-12 is a high-performance, dual-channel, 12-bit analog-to-digital converter (ADC) produced by Analog Devices, Inc. This component is designed for digitizing high-frequency, wide dynamic range signals, making it ideal for demanding applications in communications, medical imaging, and data acquisition.
It features simultaneous sampling of two channels, which is crucial for applications requiring precise timing and synchronization. The ADC operates at a sampling rate of 80 million samples per second (Msps) and offers excellent signal-to-noise ratio (SNR) and spurious free dynamic range (SFDR) performance.
