Overview
The LTC2107, produced by Analog Devices Inc., is a high-performance 16-bit analog-to-digital converter (ADC) designed for demanding applications requiring high sample rates, low noise, and high linearity. This ADC operates at a sample rate of 210 Msps, making it suitable for applications such as software-defined radios, military radio and RADAR, cellular base stations, spectral analysis, imaging systems, and automated test equipment (ATE) and instrumentation. The direct sampling front-end is optimized for high-frequency inputs, allowing direct sampling of IF frequencies up to 500 MHz with excellent performance.
