MAX1419

19-3011; Rev 1; 2/04 MAX1419 15-Bit, 65Msps ADC with -79.3dBFS Noise Floor for Baseband Applications General Description The MAX1419 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 MAX1419 is optimized for multichannel, multimode receivers, which require the ADC to meet very stringent dynamic performance requirements. With a noise floor of -79.3dBFS, the MAX1427 allows for the design of receivers with superior sensitivity. The MAX1419 achieves two-tone, spurious-free dynamic range (SFDR) of -91dBc for input tones of 10MHz and 15MHz. Its excellent signal-to-noise ratio (SNR) of 76.2dB and single-tone SFDR performance (SFDR1/SFDR2) of 93.1dBc/95.5dBc at fIN = 15MHz and a sampling rate of 65Msps make this part ideal for high-performance digital receivers. The MAX1419 operates from an analog 5V and a digital 3V supply, features a 2.56VP-P full-scale input range, and allo...
