GENERAL DESCRIPTION

–60

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.

Figure 3. Harmonic Distortion vs. Frequency at Various Supplies

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.

The devices are 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.
