LMH6522 High Performance Quad DVGA  
Check for Samples: LMH6522  
Each channel of LMH6522 has an independent,

FEATURES  
digitally controlled attenuator and a high linearity,  
differential output, amplifier. All circuitry has been  
optimized for low distortion and maximum system  
design flexibility. Power consumption is managed by  
a three-state enable pin. Individual channels can be  
disabled or placed into a Low Power Mode or a  
higher performance, High Power Mode.

Disable Function for Each Channel  
Parallel and Serial Gain Control  
The LMH6522 digitally controlled attenuator provides  
precise 1dB gain steps over a 31dB range. The digital  
attenuator can be controlled by either a SPI™ Serial  
bus or a high speed parallel bus.  
Low Power Mode for Power Management  
Flexibility  
The output amplifier has a differential output, allowing  
large signal swings on a single 5V supply. The low  
impedance output provides maximum flexibility when  
driving a wide range filter designs or analog to digital  
converters. For applications which have very large  
changes in signal level LMH6522 can support up to  
62dB of gain range by cascading channels.

Receivers  
The LMH6522 operates over the industrial

DESCRIPTION  
Performance Curve  
The LMH6522 contains four, high performance,  
digitally controlled variable gain amplifiers (DVGA). It  
has been designed for use in narrowband and  
broadband IF sampling applications. Typically, the  
LMH6522 drives a high performance ADC in a broad  
range of mixed signal and digital communication  
applications such as mobile radio and cellular base  
stations where automatic gain control (AGC) is  
required to increase system dynamic range.
