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 is
designed to drive ADCs found to in a variety of applications,
including industrial instrumentation.
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.
