MAX9922 Evaluation Kit  
Evluates:/MAX923  
General Description  
Features  
The MAX9922 evaluation kit (EV kit) is a fully assembled  
and tested PCB used to evaluate the MAX9922 and  
MAX9923 ultra-precision, high-side current-sense  
o Bidirectional or Unidirectional Current Sensing  
o Shutdown Logic Input Control  
amplifiers. An ultra-low offset voltage (V ) of 10µV  
OS  
o Multiple Gains Available  
Adjustable (MAX9922)  
25V/V (MAX9923T)  
(max) allows accurate measurement of currents at both  
extremes of sense voltages (V  
), from 10mV to  
SENSE  
100mV. The EV kit has a 1.9V to 28V input common-  
mode sense voltage range that is independent of the  
100V/V (MAX9923H)  
250V/V (MAX9923F)  
2.85V to 5.5V V  
supply.

o 2.85V to 5.5V Supply Range (V  
)
DD  
The MAX9922 EV kit comes assembled with the  
MAX9922 IC with adjustable gain, but can also evaluate  
the MAX9923 ICs with fixed gains of 25V/V  
(MAX9923T), 100V/V (MAX9923H), and 250V/V  
(MAX9923F). The MAX9922/MAX9923 are capable of  
both unidirectional and bidirectional operation.  
o 1.9V to 28V Input Common-Mode Range  
Independent of V

o Lead(Pb)-Free and RoHS Compliant  
o Fully Assembled and Tested
