General Description
The MAX1449 3.3V, 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 dif-
ferential signal path. The ADC is optimized for low-
power, high-dynamic performance in imaging and digital
communications applications. The converter operates
from a single 2.7V to 3.6V supply, consuming only
186mW while delivering a 58.5dB (typ) signal-to-noise
ratio (SNR) at a 20MHz input frequency. The fully differ-
ential input stage has a -3dB 400MHz bandwidth and
may be operated with single-ended inputs. In addition to
low operating power, the MAX1449 features a 5A
power-down mode for idle periods.
An internal 2.048V precision bandgap reference is
used to set the ADC’s full-scale range. A flexible refer-
ence structure allow’s the user to supply a buffered,
direct, or externally derived reference for applications
requiring increased accuracy or a different input volt-
age range.
Lower speed, pin-compatible versions of the MAX1449
are also available. Refer to the MAX1444 data sheet for
a 40Msps version, the MAX1446 data sheet for a
60Msps version, and the MAX1448 data sheet for 80Msps.
The MAX1449 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.
