14-Bit, 95Msps, 3.3V ADC

General Description

Features

ꢀ Direct IF Sampling Up to 400MHz

The MAX12555 is a 3.3V, 14-bit, 95Msps analog-to-digital

converter (ADC) featuring a fully differential wideband

track-and-hold (T/H) input amplifier, driving a low-noise

internal quantizer. The analog input stage accepts single-

ended or differential signals. The MAX12555 is optimized

for high dynamic performance, low power, and small

size. Excellent dynamic performance is maintained from

baseband to input frequencies of 175MHz and beyond,

making the MAX12555 ideal for intermediate-

frequency (IF) sampling applications.

ꢀ Excellent Dynamic Performance

74dB/72dB SNR at f = 3MHz/175MHz

87.4dBc/76.2dBc SFDR at f = 3MHz/175MHz

ꢀ Low Noise Floor: 74.6dBFS

ꢀ 3.3V Low-Power Operation

465mW (Single-Ended Clock Mode)

497mW (Differential Clock Mode)

300µW (Power-Down Mode)

Powered from a single 3.3V supply, the MAX12555 con-

sumes only 497mW while delivering a typical 72dB sig-

nal-to-noise ratio (SNR) performance at a 175MHz input

frequency. In addition to low operating power, the

MAX12555 features a 300µW power-down mode to

conserve power during idle periods.

ꢀ Fully Differential or Single-Ended Analog Input

ꢀ Adjustable Full-Scale Analog Input Range

0.35V to 1.10V

ꢀ Common-Mode Reference

A flexible reference structure allows the MAX12555 to use

the internal 2.048V bandgap reference or accept an

externally applied reference. The reference structure

allows the full-scale analog input range to be adjusted

from 0.35V to 1.10V. The MAX12555 provides a com-

mon-mode reference to simplify design and reduce exter-

nal component count in differential analog input circuits.

The MAX12555 supports either a single-ended or differ-

ential input clock. Wide variations in the clock duty

cycle are compensated with the ADC’s internal duty-

cycle equalizer (DCE).

ꢀ CMOS-Compatible Outputs in Two’s Complement

or Gray Code

ꢀ Data-Valid Indicator Simplifies Digital Interface

ꢀ Data Out-of-Range Indicator

ꢀ Miniature, 6mm x 6mm x 0.8mm 40-Pin Thin QFN

Package with Exposed Paddle

ꢀ Evaluation Kit Available (Order MAX12555EVKIT)

ADC conversion results are available through a 14-bit,

parallel, CMOS-compatible output bus. The digital out-

put format is pin selectable to be either two’s comple-

ment or Gray code. A data-valid indicator eliminates

external components that are normally required for reli-

able digital interfacing. A separate digital power input

accepts a wide 1.7V to 3.6V supply, allowing the

MAX12555 to interface with various logic levels.
