General Description
The MAX1191 is an ultra-low-power, dual, 8-bit,
7.5Msps 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 MAX1191 delivers a typical signal-to-noise and dis-
tortion (SINAD) of 48.6dB at an input frequency of
1.875MHz and a sampling rate of 7.5Msps while con-
suming only 12mW. This ADC operates from a 2.7V to
3.6V analog power supply. A separate 1.8V to 3.6V
supply powers the digital output driver. In addition to
ultra-low operating power, the MAX1191 features three
power-down modes to conserve power during idle peri-
ods. Excellent dynamic performance, ultra-low power,
and small size make the MAX1191 ideal for applica-
tions in imaging, instrumentation, and digital communi-
cations.
An internal 1.024V precision bandgap reference sets
the full-scale range of the ADC to ±0.512V. A flexible
reference structure allows the MAX1191 to use its inter-
nal reference or accept an externally applied reference
for applications requiring increased accuracy.
The MAX1191 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 MAX1191 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 MAX1191 are also available. Refer to the
MAX1192 data sheet for 22Msps, and the MAX1193
data sheet for 45Msps.
