The MAX19588 is a 3.3V, high-speed, high-performance analog-to-digital converter (ADC) featuring a fully differential wideband track-and-hold (T/H) and a 16-bit converter core. The MAX19588 is optimized for multichannel, multimode receivers, which require the ADC to meet very stringent dynamic performance requirements. With a -82dBFS noise floor, the MAX19588 allows for the design of receivers with supe- rior sensitivity requirements. At 100Msps, the MAX19588 achieves a 79dB signal-to- noise ratio (SNR) and an 82.1dBc/97.7dBc single-tone spurious-free dynamic range performance (SFDR1/ SFDR2) at fIN = 70MHz. The MAX19588 is not only opti- mized for excellent dynamic performance in the 2nd Nyquist region, but also for high-IF input frequencies. For instance, at 130MHz, the MAX19588 achieves an 82.3dBc SFDR and its SNR performance stays flat (within 2.3dB) up to 175MHz. This level of performance makes the part ideal for high-performance digital receivers. The MAX19588 operates from a 3.3V analog supply voltage and a 1.8V digital voltage, features a 2.56VP-P full-scale input range, and allows for a guaranteed sam- pling speed of up to 100Msps. The input track-and-hold stage operates with a 600MHz full-scale, full-power bandwidth. The MAX19588 features parallel, low-voltage CMOS- compatible outputs in two’s-complement output format. The MAX19588 is manufactured in an 8mm x 8mm, 56-pin thin QFN package with exposed paddle (EP) for low thermal resistance, and i
