Overview
The MAX1428ETN+D, produced by Analog Devices Inc./Maxim Integrated, is a high-speed, high-performance analog-to-digital converter (ADC) designed for demanding applications. This 15-bit ADC features a fully differential wideband track-and-hold (T/H) and is optimized for multichannel, multimode receivers. It is particularly suited for applications requiring stringent dynamic performance, such as cellular base-station transceiver systems and multistandard receivers. With its superior noise floor of -78.4dBFS, the MAX1428 enables the design of receivers with enhanced sensitivity.
