General Description
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. The product operates with conversion rates up to 250Msps while consuming only 975mW.
At 250Msps and an input frequency up to 250MHz, the MAX1215 achieves a spurious-free dynamic range (SFDR) of 72.4dBc. Its excellent signal-to-noise ratio (SNR) of 66dB at 10MHz remains flat (within 2dB) for input tones up to 300MHz. This ADC yields an excellent low noise floor of -67.5dBFS, which makes it ideal for wideband applications such as cable-head end receivers and power-amplifier predistortion in cellular base-station transceivers.
