MAX1428
The MAX1428 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 MAX1428 is optimized for multichannel,
multimode receivers, which require the ADC to meet very
stringent dynamic performance requirements. With a
noise floor of -78.4dBFS, the MAX1428 allows for the
design of receivers with superior sensitivity.
The MAX1428 achieves two-tone, spurious-free dynamic
range (SFDR) of -82dBc for input tones of 69MHz and
71MHz. Its excellent signal-to-noise ratio (SNR) of 73.9dB
and single-tone SFDR performance (SFDR1/SFDR2) of
83dBc/91dBc at f
IN
= 70MHz and a sampling rate of
80Msps make this part ideal for high-performance digital
receivers.
The MAX1428 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 80Msps. The
input T/H operates with a -1dB full-power bandwidth of
260MHz.
The MAX1428 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 MAX1428 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.
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 MAX1427, the MAX1428 is optimized for input
frequencies greater than f
CLK
/3.
