The

ADA4922-1

is manufactured on Analog Devices, Inc.,

proprietary, second-generation XFCB process that enables the

amplifier to achieve excellent noise and distortion performance

on high supply voltages.

The

ADA4922-1

is available in an 8-lead 3 mm × 3 mm LFCSP

as well as an 8-lead SOIC package. Both packages are equipped

with an exposed paddle for more efficient heat transfer. The

ADA4922-1

is rated to work over the extended industrial

temperature range, −40°C to +85°C.

GENERAL DESCRIPTION

The

ADA4922-1

is a differential driver for 16-bit to 18-bit

analog-to-digital converters (ADCs) that have differential input

ranges up to ±20 V. Configured as an easy-to-use, single-ended-

to-differential amplifier, the

ADA4922-1

requires no external

components to drive ADCs. The

ADA4922-1

provides essential

benefits such as low distortion and high SNR that are required

for driving ADCs with resolutions up to 18 bits.

With a wide supply voltage range (5 V to 26 V), high input

impedance, and fixed differential gain of 2, the

ADA4922-1

designed to drive ADCs found to in a variety of applications,

including industrial instrumentation.
