Overview
The LTC2299CUP, manufactured by Analog Devices Inc., is a high-performance, dual 14-bit analog-to-digital converter (ADC) designed for applications requiring high-speed and low power consumption. This ADC features a pipelined architecture and operates at a sampling rate of 80 Msps. It is ideal for digitizing high-frequency, wide dynamic range signals, making it suitable for demanding imaging and communications applications. The device operates on a single 3V supply (2.7V to 3.4V) and is known for its low power consumption of 444 mW. The LTC2299CUP is packaged in a 64-pin QFN (Quad Flat No-Lead) exposed pad package, which is RoHS compliant and lead-free.
