LTC2185CUP 16-bit ADC 2 Input 2 Pipelined 64-QFN (9x9)
LTC2185CUP is a 16-bit dual-channel simultaneous sampling pipelined ADC developed by Analog Devices (Linear Technology), supporting a maximum sampling rate of 125 MSPS and operating from a single 1.8 V analog power rail, packaged in a compact 64-QFN with exposed thermal pad. This device is optimized for high-frequency wide dynamic range analog signal digitization, delivering outstanding AC and DC performance suited for IF undersampling architectures, and supports multiple digital output modes including full-rate CMOS, DDR CMOS and DDR LVDS with flexible 1.2 V to 1.8 V adjustable output supply. Controlled via an integrated SPI configuration port, it provides selectable 1 Vp-p or 2 Vp-p differential analog input ranges, and maintains stable linearity across commercial operating temperature from 0°C to 70°C, serving as a high-performance dual ADC core for wireless communication and high-speed data acquisition hardware.
This dual simultaneous sampling high-speed ADC fits extensive high-performance electronic systems including cellular base station receiver front-ends, software-defined radio platforms, portable medical imaging equipment, multi-channel high-speed data acquisition instruments, nondestructive testing measurement hardware, radar signal processing modules, smart antenna signal capture circuits, and broadband receiver IF sampling systems. It can also be deployed in handheld test instrumentation, wireless communication transceivers and industrial broadband sensing equipment, where synchronized dual-channel analog-to-digital conversion, high linearity and low jitter are mandatory requirements to maintain high-fidelity signal digitization at high sampling frequencies.
