General Description
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 5A
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.
