The ADA4922-1 is a differential driver for 16-bit to 18-bit ADCs that have input ranges up to ±10 V. Configured in an easy-to-use, single-ended-to-differential configuration, 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), rail-to-rail output, high input impedance, and fixed gain of +1 (single ended) or +2 (differential), the ADA4922-1 is designed to drive ADCs found 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 performance on high supply voltages.

The ADA4922-1 is available in an 8-lead 3 mm × 3 mm LFCSP package 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.
