High-Dynamic-Range, 16-Bit,
100Msps ADC with -82dBFS Noise Floor
General Description
The MAX19588 is a 3.3V, high-speed, high-perfor-
mance 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 f_IN = 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 2.56V_P-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 is specified for the extended
industrial (-40°C to +85°C) temperature range.
