GENERAL DESCRIPTION

The ADA4666-2 is a dual, rail-to-rail input/output amplifier

optimized for low power, high bandwidth, and wide operating

supply voltage range applications.

The ADA4666-2 performance is guaranteed at 3.0 V, 10 V,

and 18 V power supply voltages. It is an excellent selection for

applications that use single-ended supplies of 3.3 V, 5 V, 10 V,

12 V, and 15 V, and dual supplies of ±2.5 V, ±3.3 V, and ±5 V.

The ADA4666-2 is specified over the extended industrial

temperature range (−40°C to +125°C) and is available in

8-lead MSOP and 8-lead LFCSP (3 mm × 3 mm) packages.
