GENERAL DESCRIPTION  
–70  
The ADA4950-1/ADA4950-2 are gain-selectable versions of the  
ADA4932-1/ADA4932-2 with on-chip feedback and gain resistors.  
They are ideal choices for driving high performance ADCs as single-  
ended-to-differential or differential-to-differential amplifiers. The  
output common-mode voltage is user adjustable by means of an  
internal common-mode feedback loop, allowing the ADA4950-1/  
ADA4950-2 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.

Differential gain configurations of 1, 2, and 3 are easily realized  
with internal feedback networks that are connected externally  
to set the closed-loop gain of the amplifier.

The ADA4950-x is available in a Pb-free, 3 mm × 3 mm, 16-lead  
LFCSP (ADA4950-1, single) or a Pb-free, 4 mm × 4 mm, 24-lead  
LFCSP (ADA4950-2, dual). The pinout has been optimized to  
facilitate PCB layout and minimize distortion. The ADA4950-1/  
ADA4950-2 are specified to operate over the −40°C to +105°C  
temperature range; both operate on supplies from +3 V to 5 V.  
The ADA4950-1/ADA4950-2 are fabricated using the Analog  
Devices, Inc., proprietary silicon-germanium (SiGe) complementary  
bipolar process, enabling them to achieve low levels of distortion and  
noise at low power consumption. The low offset and excellent  
dynamic performance of the ADA4950-x make it well suited for  
a wide variety of data acquisition and signal processing applications.
