WS726052M-8/TR

The WS726052 a dual high output drive CMOS operational amplifiers featured a peak output current of 350mA, and rail-to-rail output capability from a single 2.5V to 5.5V supply. This amplifier exhibits a high slew rate of 6V/μs and a gain-bandwidth product (GBP) of 11.5MHz. The WS726052 can drive typical headset levels (32Ω), as well as bias an RF power amplifier in wireless handset applications. The WS726052 is available with MSL 3 Level in MSOP-8L package and MSL 2 Level in DFN2x2-8 package. Standard products are Pb-Free and halogen-Free.
