Ultra-Low-Power, 10Msps, Dual 8-Bit ADC  
MAX192  
General Description  
Features  
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.

o Evaluation Kit Available (Order MAX19192EVKIT+)  
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.

Pin Configuration  
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.
