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
differential signal path. The ADC is optimized for low-
power, high-dynamic performance in imaging and digi-
tal communications applications. The converter
operates from a single +2.7V to +3.6V supply, consum-
ing only 186mW while delivering a 58.5dB (typ) signal-
to-noise ratio (SNR) at a 20MHz input frequency. The
fully differential input stage has a -3dB 400MHz band-
width and may be operated with single-ended inputs. In
addition to low operating power, the MAX1449 features
a 5μA 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.
