15-Bit, 65Msps ADC with -78.2dBFS
Noise Floor for IF Applications
General Description
The MAX1418 is a 5V, high-speed, high-performance
analog-to-digital converter (ADC) featuring a fully differ-
ential wideband track-and-hold (T/H) and a 15-bit con-
verter core. The MAX1418 is optimized for multichannel,
multimode receivers, which require the ADC to meet very
stringent dynamic performance requirements. With a
noise floor of -78.2dBFS, the MAX1418 allows for the
design of receivers with superior sensitivity.
The MAX1418 achieves two-tone, spurious-free dynamic
range (SFDR) of -85dBc for input tones of 69MHz and
71MHz. Its excellent signal-to-noise ratio (SNR) of 73.6dB
and single-tone SFDR performance (SFDR1/SFDR2) of
88dBc/92dBc at f_IN = 70MHz and a sampling rate of
65Msps make this part ideal for high-performance digital
receivers.
The MAX1418 operates from an analog 5V and a digital
3V supply, features a 2.56V_P-P full-scale input range,
and allows for a sampling speed of up to 65Msps. The
input T/H operates with a -1dB full-power bandwidth of
260MHz.
The MAX1418 features parallel, CMOS-compatible out-
puts in two’s-complement format. To enable the interface
with a wide range of logic devices, this ADC provides a
separate output driver power-supply range of 2.3V to
3.5V. The MAX1418 is manufactured in an 8mm x 8mm,
56-pin QFN package with exposed paddle (EP) for low
thermal resistance, and is specified for the extended
industrial (-40°C to +85°C) temperature range.
Note that IF parts MAX1418, MAX1428, and MAX1430
(see Pin-Compatible Higher/Lower Speed Versions
Selection table) are recommended for applications that
require high dynamic performance for input frequen-
cies greater than f_CLK/3. Unlike its baseband counter-
part MAX1419, the MAX1418 is optimized for input
frequencies greater than f_CLK/3.
