The ADA4922-1 is a differential driver for 16-bit to 18-bit
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 is
designed to drive ADCs found to in a variety of applications,
including industrial instrumentation.
The ADA4922-1 is manufactured on ADI’s 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.
