The MAX19586 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 MAX19586 is optimized for
multichannel, multimode receivers, which require the
ADC to meet very stringent dynamic performance
requirements. With a -82dBFS noise floor, the
MAX19586 allows for the design of receivers with superior
sensitivity requirements.
At 80Msps, the MAX19586 achieves a 79.2dB signal-to-noise
ratio (SNR) and an 84.3dBc/100dBc single-tone
spurious-free dynamic range (SFDR) performance
(SFDR1/SFDR2) at fIN = 70MHz. The MAX19586 is not
only optimized for excellent dynamic performance in
the 2nd Nyquist region, but also for high-IF input frequencies.
For instance, at 130MHz, the MAX19586
achieves an 82.5dBc SFDR and its SNR performance
stays flat (within 2.5dB) throughout the 4th Nyquist
region. This level of performance makes the part ideal
for high-performance digital receivers.
The MAX19586 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 sampling
speed of up to 80Msps. The input track-and-hold
stage operates with a 600MHz full-scale, full-power
bandwidth.
The MAX19586 features parallel, low-voltage CMOS-compatible
outputs in two's-complement output format.
The MAX19586 is manufactured in an 8mm x 8mm,
56-pin thin QFN package with exposed paddle (EP) for
low thermal resistance, and is specified for the extended
industrial (-40°C to +85°C) temperature range.
