Description
The MAX1429 is a 5V, high-speed, high-performance
analog-to-digital converter (ADC) featuring a fully differential
wideband track-and-hold (T/H) and a 15-bit converter
core. The MAX1429 is optimized for multichannel,
multimode receivers, which require the ADC to meet very
stringent dynamic performance requirements. With a
noise floor of -77.7dBFS, the MAX1429 allows for the
design of receivers with superior sensitivity.
The MAX1429 achieves two-tone, spurious-free dynamic
range (SFDR) of -100dBc for input tones of 10MHz and
15MHz. Its excellent signal-to-noise ratio (SNR) of 75.1dB
and single-tone SFDR performance (SFDR1/SFDR2) of
90dBc/94dBc at fIN = 15MHz and a sampling rate of
100Msps make this part ideal for high-performance digital
receivers.
The MAX1429 operates from an analog 5V and a digital
3V supply, features a 2.2VP-P full-scale input range,
and allows for a sampling speed of up to 100Msps. The
input T/H operates with a -1dB full-power bandwidth of
260MHz.
The MAX1429 features parallel, CMOS-compatible outputs
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 MAX1429 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 in the full datasheet) are recommended for applications that
require high dynamic performance for input frequencies
greater than fCLK/3. The MAX1429 is optimized for
input frequencies of less than fCLK/3.
