General Description

The MAX1213 is a monolithic, 12-bit, 170Msps analog-to-digital converter (ADC) optimized for outstanding dynamic performance at high-IF frequencies up to 300MHz. The product operates with conversion rates up to 170Msps while consuming only 788mW.

At 170Msps and an input frequency up to 250MHz, the MAX1213 achieves a spurious-free dynamic range (SFDR) of 72.9dBc. Its excellent signal-to-noise ratio (SNR) of 66.2dB at 10MHz remains flat (within 2dB) for input tones up to 250MHz. This ADC yields an excellent low-noise floor of -68dBFS, which makes it ideal for wideband applications such as cable head-end receivers and power-amplifier predistortion in cellular base-station transceivers.
