General Description
The MAX1196 is a 3V, dual 8-bit analog-to-digital con-
verter (ADC) featuring fully differential wideband track-
and-hold (T/H) inputs, driving two ADCs. The MAX1196
is optimized for low power, small size, and high-dynamic
performance for applications in imaging, instrumenta-
tion, and digital communications. This ADC operates
from a single 2.7V to 3.6V supply, consuming only
87mW while delivering a typical signal-to-noise and dis-
tortion (SINAD) of 48.4dB at an input frequency of
20MHz and a sampling rate of 40Msps. The T/H driven
input stages incorporate 400MHz (-3dB) input ampli-
fiers. The converters can also be operated with single-
ended inputs. In addition to low operating power, the
MAX1196 features a 3mA sleep mode as well as a
0.1μA power-down mode to conserve power during idle
periods.
An internal 2.048V precision bandgap reference sets
the full-scale range of the ADC. A flexible reference
structure allows the use of this internal or an externally
applied reference, if desired for applications requiring
increased accuracy or a different input voltage range.
The MAX1196 features parallel, multiplexed, CMOS-
compatible three-state outputs. The digital output format
can be set to two’s complement or straight offset binary
through a single control pin. The device provides for a
separate output power supply of 1.7V to 3.6V for flexible
interfacing. The MAX1196 is available in a 7mm
×
7mm,
48-pin TQFP package, and is specified for the extended
industrial (-40°C to +85°C) temperature range.
Pin-compatible, nonmultiplexed higher speed versions of
the MAX1196 are also available. Refer to the MAX1198
data sheet for 100Msps, the MAX1197 data sheet for
60Msps, and the MAX1195 data sheet for 40Msps.
For a 10-bit, pin-compatible upgrade, refer to the
MAX1186 data sheet. With the N.C. pins of the
MAX1196 internally pulled down to ground, this ADC
becomes a drop-in replacement for the MAX1186.
