General Description

The MAX1214N is a monolithic, 12-bit, 210Msps analog-to-digital converter (ADC) optimized for outstanding dynamic performance at high-IF frequencies beyond 300MHz. The product operates with conversion rates up to 210Msps while consuming only 799mW.

At 210Msps and an input frequency up to 100MHz, the MAX1214N achieves an 81.3dBc spurious-free dynamic range (SFDR) with excellent 67dB signal-to-noise ratio (SNR) that remains flat (within 2dB) for input tones up to 250MHz. This makes it ideal for wideband applications such as communications receivers, cable-head end receivers, and power-amplifier predistortion in cellular base-station transceivers.
