12-Bit, 95Msps, 3.3V ADC  
General Description  
Features  
♦ Direct IF Sampling Up to 400MHz  
♦ Excellent Dynamic Performance  
The MAX19538 is a 3.3V, 12-bit, 95Msps analog-to-digi-  
tal converter (ADC) featuring a fully differential wide-  
band track-and-hold (T/H) input amplifier, driving a  
low-noise internal quantizer. The analog input accepts  
single-ended or differential signals. The MAX19538 is  
optimized for low power, small size, and high dynamic  
performance. Excellent dynamic performance is main-  
tained from baseband to input frequencies of 175MHz  
and beyond, making the MAX19538 ideal for intermedi-  
ate frequency (IF) sampling applications.

♦ 3.3V Low-Power Operation  
465mW (Single-Ended Clock Mode)  
492mW (Differential Clock Mode)  
63µW (Power-Down Mode)  
Powered from a single 3.3V supply, the MAX19538 con-  
sumes only 492mW while delivering a typical 68.4dB  
signal-to-noise ratio (SNR) performance at a 175MHz  
input frequency. In addition to low operating power, the  
MAX19538 features a 63µW power-down mode to con-  
serve 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  
♦ CMOS-Compatible Outputs in Two’s Complement  
A flexible reference structure allows the MAX19538 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 MAX19538 provides a com-  
mon-mode reference to simplify design and reduce exter-  
nal component count in differential analog input circuits.

♦ Data-Valid Indicator Simplifies Digital Design  
♦ Data Out-of-Range Indicator  
♦ Miniature 6mm x 6mm x 0.8mm 40-Pin Thin QFN  
Package with Exposed Paddle  
♦ Evaluation Kit Available (Order MAX1211EVKIT)  
The MAX19538 supports either a single-ended or differ-  
ential input clock drive. The internal clock duty-cycle  
equalizer accepts a wide range of clock duty cycles.

PKG CODE  
Analog-to-digital conversion results are available  
through a 12-bit, parallel, CMOS-compatible output bus.  
The digital output format is pin selectable to be either  
two’s complement or Gray code. A data-valid indicator  
eliminates external components that are normally  
required for reliable digital interfacing. A separate digital  
power input accepts a wide 1.7V to 3.6V supply allow-  
ing the MAX19538 to interface with various logic levels.
