General Description
The MAX1420, +3.3V, 12-bit analog-to-digital converter
(ADC) features a fully-differential input, pipelined, 12-
stage ADC architecture with wideband track-and-hold
(T/H) and digital error correction, incorporating a fully-
differential signal path. The MAX1420 is optimized for
low-power, high dynamic performance applications in
imaging and digital communications. The converter
operates from a single +3.3V supply, and consumes
only 221mW. The fully-differential input stage has a
small signal -3dB bandwidth of 400MHz and may be
operated with single-ended inputs.
An internal +2.048V precision bandgap reference sets
the full-scale range of the ADC. A flexible reference
structure accommodates an internal reference, or
externally applied buffered or unbuffered reference for
applications that require increased accuracy and a dif-
ferent input voltage range.
In addition to low operating power, the MAX1420 fea-
tures two power-down modes: reference power-down
and shutdown mode. In reference power-down, the
internal bandgap reference is deactivated, which
results in a typical 2mA supply current reduction. A full
shutdown mode is available to maximize power savings
during idle periods.
The MAX1420 provides parallel, offset binary, CMOS-
compatible three-state outputs.
The MAX1420 is available in a 7mm
7mm, 48-pin
TQFP package, and is specified over the commercial
(0
°
C to +70
°
C) and the extended industrial (-40
°
C to
+85
°
C) temperature range.
Pin-compatible lower speed versions of the MAX1420
are also available. Please refer to the MAX1421 data
sheet for 40Msps and the MAX1422 data sheet for
20Msps.
