10-Bit, 60Msps, 3.0V, Low-Power  
ADC with Internal Reference  
General Description  
Features  
The MAX1446 10-bit, 3V analog-to-digital converter  
(ADC) features a fully differential input, a pipelined 10-  
stage ADC architecture with digital error correction and  
wideband track and hold (T/H) incorporating a fully dif-  
ferential signal path. This ADC is optimized for low-  
power, high dynamic performance applications in  
imaging and digital communications. The MAX1446  
operates from a single 2.7V to 3.6V supply, consuming  
only 90mW 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 MAX1446 features a 5µA  
power-down mode for idle periods.

ꢀ 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 full-scale range. A flexible reference  
structure allows the user to supply a buffered, direct or  
externally derived reference for applications requiring  
increased accuracy or a different input voltage range.  
Lower and higher speed, pin-compatible versions of  
the MAX1446 are also available. Refer to the MAX1444  
data sheet for a 40Msps version and the MAX1448 data  
sheet for a 80Msps version.

32 TQFP  
The MAX1446 has parallel, offset binary, three-state  
outputs that can be operated from 1.7V to 3.3V 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.
