General Description

The MAX1427 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 MAX1427 is optimized for multichannel,

multimode receivers, which require the ADC to meet very

stringent dynamic performance requirements. With a

noise floor of -79.3dBFS, the MAX1427 allows for the

design of receivers with superior sensitivity.

The MAX1427 achieves two-tone, spurious-free dynamic

range (SFDR) of -91dBc for input tones of 10MHz and

15MHz. Its excellent signal-to-noise ratio (SNR) of 76.1dB

and single-tone SFDR performance (SFDR1/SFDR2) of

93.5dBc/94.5dBc at f

= 15MHz and a sampling rate of

80Msps make this part ideal for high-performance digital

receivers.

The MAX1427 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

200MHz.

The MAX1427 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 MAX1427 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. The MAX1427 is optimized for

input frequencies of less than f

CLK

/3.
