MAX9939  
SPI Programmable-Gain Amplifier  
with Input V Trim and Output Op Amp  
OS  
General Description  
Features  
The MAX9939 is a general-purpose, differential-input  
programmable-gain amplifier (PGA) that is ideal for con-  
ditioning a variety of wide dynamic range signals such  
as those found in motor current-sense, medical instru-  
mentation, and sonar data acquisition applications. It  
features programmable differential gains from 0.2V/V to  
157V/V, input offset-voltage compensation, and an out-  
put amplifier that can be configured either as a high-  
order active filter or to provide a differential output.  
o SPI-Programmable Gains: 0.2V/V to 157V/V  
o Extremely Low Gain Tempco  
o Integrated Amplifier for R/C Programmable Active  
Filter  
o Input Offset-Voltage Compensation  
o Input Protection to 16V  
o 13µA Software Shutdown Mode  
The PGA is optimized for high-signal bandwidth and its  
gain can be programmed to be 0.2V/V, 1V/V, 10V/V,  
20V/V, 30V/V, 40V/V, 60V/V, 80V/V, 119V/V, and 157V/V.  
Precision resistor matching provides extremely low gain  
tempco and high CMRR. Although the MAX9939 oper-  
o -40°C to +125°C Operating Temperature Range  
o 10-Pin µMAX Package  
ates from a single supply V  
between 2.9V to 5.5V, it  
CC  
can process signals both above and below ground due  
to the use of an input level-shifting amplifier stage.  
Furthermore, its inputs are protected to 16V, allowing it  
to withstand fault conditions and signal overranges.

10 µMAX  
The output amplifier is designed for high bandwidth  
and low-bias currents, making it ideal for use in multi-  
ple-feedback active filter topologies that offer much  
higher Qs and stopband attenuation than Sallen-Key  
architectures.

+Denotes a lead(Pb)-free/RoHS-compliant package.  
The MAX9939 draws 3.4mA of quiescent supply current  
at 5V, and includes a software-programmable shut-  
down mode that reduces its supply current to only  
13µA. The MAX9939 is available in a 10-pin µMAX®  
package and operates over the -40°C to +125°C auto-  
motive temperature range.
