FEATURES  
DESCRIPTION  
The LMH6518 is a digitally controlled variable gain  
amplifier whose total gain can be varied from −1.16  
dB to 38.8 dB for a 40 dB range in 2 dB steps. The  
−3 dB bandwidth is 900 MHz at all gains. Gain  
accuracy at each setting is typically 0.1 dB. When

Min Gain −1.16 dB  
Gsample/second (Gsps) ADC with adjustable full  
scale (FS) range, the LMH6518 gain adjustment will  
accommodate full scale input signals from 6.8 mVPP  
to 920 mVPP to get 700 mVPP nominal at the ADC  
input. The Auxiliary output (“+OUT Aux” and “−OUT  
Aux”) follows the Main output and is intended for use  
in Oscilloscope trigger function circuitry but may have  
other uses in other applications.  
Max Gain 38.8 dB

Input-Referred Noise (Max Gain) 0.98 nV/√Hz  
Over-Voltage Clamps for Fast Recovery  
The LMH6518 gain is programmed via a SPI-1  
compatible serial bus. A signal path combined gain  
resolution of 8.5 mdB can be achieved when the  
LMH6518’s gain and the Gsps ADC’s FS input are  
both manipulated. Inputs and outputs are DC-  
coupled. The outputs are differential with individual  
Common Mode (CM) voltage control (for Main and  
Auxiliary outputs) and have a selectable bandwidth  
limiting circuitry (common to both Main and Auxiliary)  
of 20, 100, 200, 350, 650, 750 MHz or full bandwidth.
