MAX1418

19-3022; Rev 1; 2/04 MAX1418 15-Bit, 65Msps ADC with -78.2dBFS Noise Floor for IF Applications General Description The MAX1418 is a 5V, high-speed, high-performance analog-to-digital converter (ADC) featuring a fully differential wideband track-and-hold (T/H) and a 15-bit converter core. The MAX1418 is optimized for multichannel, multimode receivers, which require the ADC to meet very stringent dynamic performance requirements. With a noise floor of -78.2dBFS, the MAX1418 allows for the design of receivers with superior sensitivity. The MAX1418 achieves two-tone, spurious-free dynamic range (SFDR) of -85dBc for input tones of 69MHz and 71MHz. Its excellent signal-to-noise ratio (SNR) of 73.6dB and single-tone SFDR performance (SFDR1/SFDR2) of 88dBc/92dBc at fIN = 70MHz and a sampling rate of 65Msps make this part ideal for high-performance digital receivers. The MAX1418 operates from an analog 5V and a digital 3V supply, features a 2.56VP-P full-scale input range, and allows for a s...
