GENERAL DESCRIPTION  
–80  
The ADA4939 is a low noise, ultralow distortion, high speed  
differential amplifier. It is an ideal choice for driving high  
performance ADCs with resolutions up to 16 bits from dc to  
100 MHz. The output common-mode voltage is user adjustable  
by means of an internal common-mode feedback loop, allowing  
the ADA4939 output to match the input of the ADC. The internal  
feedback loop also provides exceptional output balance as well as  
suppression of even-order harmonic distortion products.

FREQUENCY (MHz)  
With the ADA4939, differential gain configurations are easily  
realized with a simple external feedback network of four resistors  
that determine the closed-loop gain of the amplifier.  
Figure 3. Harmonic Distortion vs. Frequency  
The ADA4939 is available in a Pb-free, 3 mm × 3 mm 16-lead  
LFCSP (ADA4939-1, single) or a Pb-free, 4 mm × 4 mm 24-lead  
LFCSP (ADA4939-2, dual). The pinout has been optimized to  
facilitate PCB layout and minimize distortion. The ADA4939-1  
and the ADA4939-2 are specified to operate over the −40°C to  
+105°C temperature range; both operate on supplies between  
3.3 V and 5 V.  
The ADA4939 is fabricated using Analog Devices, Inc., proprietary  
silicon-germanium (SiGe), complementary bipolar process,  
enabling it to achieve very low levels of distortion with an input  
voltage noise of only 2.3 nV/√Hz. The low dc offset and excellent  
dynamic performance of the ADA4939 make it well suited for a  
wide variety of data acquisition and signal processing applications.
