STMicroelectronics RHF350A
The RHF350A device is a current feedback, single operational amplifier that uses very high-speed complementary technology to provide a bandwidth of up to 550 MHz while drawing only 4 mA of quiescent current. With a slew rate of 940 V/µs and an output stage optimized for driving a standard 100 Ω load, this circuit is highly suitable for applications where speed and power-saving are the main requirements. The RHF350A is mounted in a Flat-8 hermetic package.| Part No. | RHF350A |
