MAX1444

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.

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.

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.
