MAX12555

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.

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

sumes only 497mW while delivering a typical 72.1dB

signal-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.

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).

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.

The MAX12555 is available in a 6mm x 6mm x 0.8mm,

40-pin thin QFN package with exposed paddle (EP),

and is specified for the extended industrial (-40°C to

+85°C) temperature range.
