GENERAL DESCRIPTION

The ADA4927-1/ADA4927-2 are low noise, ultralow distortion,

high speed current feedback differential amplifiers that are ideal

choices for driving high performance ADCs with resolutions up

to 16 bits from dc to 100 MHz. The ADA4927-1/ADA4927-2

adjustable output common-mode levels can easily be matched

to the required ADC input common-mode levels. The internal

common-mode feedback loop provides exceptional output

balance and suppression of even-order distortion products.

consumption than comparable voltage feedback amplifiers.

The ADA4927-1/ADA4927-2 are fabricated using Analog

Devices, Inc. proprietary silicon-germanium (SiGe),

complementary bipolar process, enabling very low levels of

distortion with an input voltage noise of only 1.3 nV/√Hz. The

low dc offset and excellent dynamic performance of the

ADA4927-1/ADA4927-2 make them well suited for a wide

variety of data acquisition and signal processing applications.

Differential gain configurations are easily realized with the

ADA4927-1/ADA4927-2 using simple external feedback

networks comprised of four resistors. The current feedback

architecture provides loop gain that is nearly independent of

closed-loop gain, thus achieving wide bandwidth, low

distortion, and low noise at high gains, all at lower power

The ADA4927-1 is available in a Pb-free, 3 mm × 3 mm 16-lead

LFCSP and the ADA4927-2 in a Pb-free, 4 mm × 4 mm 24-lead

LFCSP. The pinouts have been optimized to facilitate PCB

layout and to minimize distortion. They are specified to operate

over the −40°C to +105°C temperature range.
