Ultra-Low-Power, 10Msps, Dual 8-Bit ADC
General Description
The MAX19192 is an ultra-low-power, dual, 8-bit, 10Msps
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
MAX19192 delivers a typical signal-to-noise and distor-
tion (SINAD) of 48.6dB at an input frequency of
1.875MHz and a sampling rate of 10Msps while consum-
ing only 15.3mW. 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 MAX19192 features three power-
down modes to conserve power during idle periods.
Excellent dynamic performance, ultra-low power, and
small size make the MAX19192 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 MAX19192 to use its
internal reference or accept an externally applied refer-
ence for applications requiring increased accuracy.
The MAX19192 features parallel, multiplexed, CMOS-
compatible three-state outputs. The digital output for-
mat is offset binary. A separate digital power input
accepts a voltage from 1.8V to 3.6V for flexible interfac-
ing to different logic levels. The MAX19192 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 MAX19192 are also available. Refer to
the MAX1191 data sheet for 7.5Msps, the MAX1192
data sheet for 22Msps, and the MAX1193 data sheet
for 45Msps.
