Overview
The MAX1215 is a monolithic, 12-bit, 250Msps analog-to-digital converter (ADC) optimized for outstanding dynamic performance at high-IF frequencies up to 300MHz. This ADC is designed for wideband applications, such as cable-head end receivers and power-amplifier predistortion in cellular base-station transceivers. It operates with a single 1.8V supply and features low power consumption and excellent noise characteristics.
