10-Bit, 40Msps, 3.0V, Low-Power  
ADC with Internal Reference  
MAX14  
General Description  
Features  
The MAX1444 10-bit, 3V analog-to-digital converter  
(ADC) features a pipelined 10-stage ADC architecture  
with fully differential wideband track-and-hold (T/H)  
input and digital error correction incorporating a fully  
differential signal path. This ADC is optimized for low-  
power, high dynamic performance applications in  
imaging and digital communications. The MAX1444  
operates from a single 2.7V to 3.6V supply, consuming  
only 57mW while delivering a 59.5dB signal-to-noise  
ratio (SNR) at a 20MHz input frequency. The fully differ-  
ential input stage has a 400MHz -3dB bandwidth and  
may be operated with single-ended inputs. In addition  
to low operating power, the MAX1444 features a 5µA  
power-down mode for idle periods.

o On-Chip 2.048V Precision Bandgap Reference  
o CMOS-Compatible Three-State Outputs  
o 32-Pin TQFP Package  
An internal 2.048V precision bandgap reference is  
used to set the ADC full-scale range. A flexible refer-  
ence structure allows the user to supply a buffered,  
direct, or externally derived reference for applications  
requiring increased accuracy or a different input volt-  
age range.  
o Evaluation Kit Available  
Ordering Information  
Higher speed, pin-compatible versions of the MAX1444  
are also available. Please refer to the MAX1446 data  
sheet (60Msps) and the MAX1448 data sheet  
(80Msps).

The MAX1444 has parallel, offset binary, CMOS-com-  
patible three-state outputs that can be operated from  
1.7V to 3.6V to allow flexible interfacing. The device is  
available in a 5x5mm 32-pin TQFP package and is  
specified over the extended industrial (-40°C to +85°C)  
temperature range.
