Precision Transimpedance Logarithmic  
Amplifier with Over 5 Decades of Dynamic Range  
General Description  
Features  
The MAX4207 logarithmic amplifier computes the log  
ratio of an input current relative to a reference current  
(externally or internally generated) and provides a cor-  
responding voltage output with a default -0.25V/decade  
scale factor. The device operates from dual 2.7V to  
5.5V supplies and is capaꢀle of measuring five  
decades of input current across a 10nA to 1mA range.  
♦ ±2.7V to ±5.5V Dual-Supply Operation  
♦ 5 Decades of Dynamic Range (10nA to 1mA)  
♦ Monotonic Over a 1nA to 1mA Range  
♦ -0.25V/Decade Internally Trimmed Output Scale  
Factor  
The MAX4207’s uncommitted op amp can ꢀe used for  
a variety of functions, including filtering noise, adding  
offset, and adding additional gain. A 0.5V reference is  
also included to generate an optional precision current  
reference using an external resistor, which adjusts the  
log intercept of the MAX4207. The output-offset voltage  
and the adjustaꢀle scale factor are also set using exter-  
nal resistors.  
♦ Adjustable Output Scale Factor  
♦ Adjustable Output Offset Voltage  
♦ Internal 10nA to 10µA Reference Current Source  
♦ Input Amplifiers Summing Nodes at Ground  
♦ Small 16-Pin Thin QFN Package (4mm x 4mm x  
0.8mm)  
The MAX4207 is availaꢀle in a space-saving 16-pin thin  
QFN package (4mm x 4mm x 0.8mm), and is specified  
for operation over the -40°C to +85°C extended temper-  
ature range.  
♦ -40°C to +85°C Operating Temperature Range  
♦ Evaluation Kit Available (Order MAX4206EVKIT)
