10-Bit, 80Msps, Single 3.0V, Low-Power  
ADC with Internal Reference  
General Description  
Features  
The MAX1448 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  
differential signal path. The ADC is optimized for low-  
power, high dynamic performance in imaging and digi-  
tal communications applications. The converter  
operates from a single 2.7V to 3.6V supply, consuming  
only 120mW while delivering a 59dB (typ) signal-to-  
noise ratio (SNR) at a 20MHz input frequency. The fully  
differential input stage has a -3dB 400MHz bandwidth  
and may be operated with single-ended inputs. In addi-  
tion to low operating power, the MAX1448 features a  
5µA power-down mode for idle periods.

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.  
Evaluation Kit Available (MAX1448 EV Kit)  
Ordering Information  
Lower speed, pin-compatible versions of the MAX1448  
are also available. Refer to the MAX1444 data sheet for  
a 40Msps version and to the MAX1446 data sheet for a  
60Msps version.

32 TQFP  
The MAX1448 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.
