Ultra-Low-Power, 45Msps, Dual 8-Bit ADC
General Description
The MAX1193 is an ultra-low-power, dual, 8-bit,
45Msps 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 MAX1193 delivers a typical signal-to-noise and dis-
tortion (SINAD) of 48.5dB at an input frequency of
5.5MHz and a sampling rate of 45Msps while consum-
ing only 57mW. 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 MAX1193 features three power-
down modes to conserve power during idle periods.
Excellent dynamic performance, ultra-low power, and
small size make the MAX1193 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 MAX1193 to use its inter-
nal reference or accept an externally applied reference
for applications requiring increased accuracy.
The MAX1193 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 MAX1193 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 MAX1193 are also available. Refer to the
MAX1191 data sheet for 7.5Msps, and the MAX1192
data sheet for 22Msps.
