The MAX1211 is a 3.3V, 12-bit analog-to-digital converter
(ADC) featuring a fully differential wideband track-and-hold (T/H) input, driving the internal quantizer. The
MAX1211 is optimized for low power, small size, and
high dynamic performance in intermediate frequency
(IF) sampling applications. This ADC operates from a
single 3.0V to 3.6V supply, consuming only 340mW
while delivering a typical signal-to-noise ratio (SNR) performance
of 66.8dB at a 175MHz input frequency. The
T/H-driven input stage accepts single-ended or differential
inputs. In addition to low operating power, the
MAX1211 features a 0.15mW power-down mode to conserve
power during idle periods.
A flexible reference structure allows the MAX1211 to
use its internal precision bandgap reference or accept
an externally applied reference. A common-mode reference
is provided to simplify design and reduce external
component count in differential analog input circuits.
The MAX1211 supports both a single-ended and differential
input clock drive. Wide variations in the clock
duty cycle are compensated with the ADC's internal
duty-cycle equalizer.
The MAX1211 features parallel, CMOS-compatible outputs.
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 power
input for the digital outputs accepts a voltage from 1.7V
to 3.6V for flexible interfacing with various logic levels.
The MAX1211 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.
