ADI ADA4666-2ARMZ-R7

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.
