General Description
The MAX1192 is an ultra-low-power, dual, 8-bit, 22Msps
analog-to-digital converter (ADC). The device features
two fully differential wideband track-and-hold (T/H) inputs.
These inputs have a 440MHz bandwidth and accept fully
differential or single-ended signals. The MAX1192 deliv-
ers a typical signal-to-noise and distortion (SINAD) of
48.6dB at an input frequency of 5.5MHz and a sampling
rate of 22Msps while consuming only 27.3mW. This ADC
operates from a 2.7V to 3.6V analog power supply. A sep-
arate 1.8V to 3.6V supply powers the digital output driver.
In addition to ultra-low operating power, the MAX1192
features three power-down modes to conserve power
during idle periods. Excellent dynamic performance,
ultra-low power, and small size make the MAX1192 ideal
for applications in imaging, instrumentation, and digital
communications.
An internal 1.024V precision bandgap reference sets
the full-scale range of the ADC to ±0.512V. A flexible
reference structure allows the MAX1192 to use its inter-
nal reference or accept an externally applied reference
for applications requiring increased accuracy.
The MAX1192 features parallel, multiplexed, CMOS-
compatible tri-state outputs. The digital output format is
offset binary. A separate digital power input accepts a
voltage from 1.8V to 3.6V for flexible interfacing to dif-
ferent logic levels. The MAX1192 is available in a 5mm
× 5mm, 28-pin thin QFN package, and is specified for
the extended industrial (-40°C to +85°C) temperature
range.
For higher sampling frequency applications, refer to the
MAX1195–MAX1198 dual 8-bit ADCs. Pin-compatible
versions of the MAX1192 are also available. Refer to the
MAX1191 data sheet for 7.5Msps, and the MAX1193
data sheet for 45Msps.
