Overview
The LTC2182CUP, manufactured by Analog Devices Inc., is a high-performance, 16-bit, dual-channel analog-to-digital converter (ADC) designed for applications requiring simultaneous sampling of high-frequency, wide dynamic range signals. This ADC features a pipelined architecture and operates at a sampling rate of 65 MS/s. It is particularly suited for demanding communications and data acquisition applications due to its excellent AC performance, including a signal-to-noise ratio (SNR) of 77 dB and a spurious free dynamic range (SFDR) of 90 dB. The device is available in a 64-pin QFN package and supports various digital output formats such as CMOS, DDR CMOS, and DDR LVDS.
