♦ 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,  
ma king the MAX12555 id e a l for inte rme d ia te -  
frequency (IF) sampling applications.

♦ Low Noise Floor: 74.7dBFS  
♦ 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 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.  
♦ 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.  
♦ 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  
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).  
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  
a c c e p ts a wid e 1.7V to 3.6V s up p ly, a llowing the  
MAX12555 to interface with various logic levels.
