MAX1446

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.

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, the MAX1448 data

sheet for an 80Msps version, and the MAX1449 data

sheet for a 105Msps version.

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 5mm x

5mm, 32-pin TQFP package and is specified over the

extended industrial (-40°C to +85°C) and automotive

(-40°C to +105°C) temperature ranges.
