19-4802; Rev 2; 9/04  
10-Bit, 105Msps, Single 3.3V, Low-Power  
ADC with Internal Reference  
General Description  
Features  
The MAX1449 3.3V, 10-bit analog-to-digital converter  
(ADC) features a fully differential input, a pipelined 10-  
stage ADC architecture with wideband track-and-hold  
(T/H), and digital error correction incorporating a fully dif-  
ferential signal path. The ADC is optimized for low-  
power, high-dynamic performance in imaging and digital  
communications applications. The converter operates  
from a single 2.7V to 3.6V supply, consuming only  
186mW while delivering a 58.5dB (typ) signal-to-noise  
ratio (SNR) at a 20MHz input frequency. The fully differ-  
ential input stage has a -3dB 400MHz bandwidth and  
may be operated with single-ended inputs. In addition to  
low operating power, the MAX1449 features a 5µA  
power-down mode for idle periods.

♦ 400MHz -3dB Input Bandwidth  
♦ On-Chip 2.048V Precision Bandgap Reference  
♦ CMOS-Compatible Three-State Outputs  
♦ 32-Pin TQFP Package  
An internal 2.048V precision bandgap reference is  
used to set the ADC’s full-scale range. A flexible refer-  
ence structure allow’s the user to supply a buffered,  
direct, or externally derived reference for applications  
requiring increased accuracy or a different input volt-  
age range.  
♦ Evaluation Kit Available (MAX1448 EV Kit)  
Ordering Information  
Lower speed, pin-compatible versions of the MAX1449  
are also available. Refer to the MAX1444 data sheet for  
a 40Msps version, the MAX1446 data sheet for a  
60Msps version, and the MAX1448 data sheet for 80Msps.

The MAX1449 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 5mm x 5mm 32-pin TQFP package and is  
specified over the extended industrial (-40°C to +85°C)  
temperature range.
