High-Dynamic-Range, 16-Bit,
100Msps ADC with -82dBFS Noise Floor
MAX1958
General Description
Features
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.
♦ 100Msps Conversion Rate
♦ -82dBFS Noise Floor
♦ Excellent Low-Noise Characteristics

♦ Less than 0.1ps Sampling Jitter
♦ 1275mW Power Dissipation
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/

IN
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.
