The AD8641 is available in 5-lead SC70 and 8-lead SOIC lead-free packages. The AD8642 is available in 8-lead MSOP and 8-lead SOIC lead-free packages. The AD8643 is available in 14-lead SOIC and 16-lead, 3 mm × 3 mm, LFCSP lead-free packages. +IN A 3 16 NIC The AD8641/AD8642/AD8643 are suitable for applications utilizing multichannel boards that require low power to manage heat. Other applications include photodiodes, ATE reference level drivers, battery management, and industrial controls. AD8642 15 OUT A The AD8641/AD8642/AD8643 are low power, precision JFET input amplifiers featuring extremely low input bias current and rail-to-rail output. The ability to swing nearly rail-to-rail at the input and rail-to-rail at the output enables designers to buffer complementary metal-oxide semiconductor digital-to-analog converters (CMOS DACs), ASICs, and other wide output swing devices in single-supply systems. The outputs remain stable with capacitive loads of more than 500 pF. –IN A 2 OUT B 6 GENERAL DESCRIPTION 05072-064 Figure 3. 8-Lead SOIC (R-8) 05072-103 Data Sheet Low Power, Rail-to-Rail Output, Precision JFET Amplifiers AD8641/AD8642/AD8643 Figure 6. 16-Lead LFCSP (CP-16-27) (Not Drawn to Scale) Rev.

This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability. THERMAL RESISTANCE θJA is specified for the worst-case conditions, that is, a device soldered in a circuit board for surface-mount packages. This was measured using a standard 4-layer board. For the LFCSP, solder the exposed pad to a copper plane, which should be connected to V+. Table 4.
