♦ 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.
