Figure 2. 8-Lead LFCSP 10000 VSY = 18V 1000 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. 100 –40°C +25°C +85°C +125°C 10 1 0.001 0.01 0.1 1 10 100 LOAD CURRENT (mA) Figure 3.
