Операционные усилители MAX4232AUA+

Операционный усилитель , выход с полным размахом напряжения, 2 Усилителя, 10 МГц, 10 В/мкс

The MAX4232AUA+ is a high output drive, rail to rail I/O, dual CMOS operational amplifier (op-amp) with shutdown mode in 8 pin µMAX package. This amplifier exhibits high slew rate of 10V/µs and gain bandwidth product (GBWP) of 10MHz. The MAX4232 can drive typical headset levels (32ohm) as well as bias an RF power amplifier (PA) in wireless handset applications. This op-amp is designed to be part of RF PA control circuitry and biasing RF power amplifiers in wireless headsets. It is also used in audio hands free car phones kits, digital to analogue converter buffers, transformer/line drivers and high bandwidth applications.
