Description
Current Operational Amplifier The HA-2542 is a wideband, high slew rate, monolithic operational amplifier featuring an outstanding combination of speed, bandwidth, and output drive capability. Utilizing the advantages of the Intersil D.I. technology this amplifier offers 350V/µs slew rate, 70MHz gain bandwidth, and ±100mA output current. Application of this device is further enhanced through stable operation down to closed loop gains of 2.
For additional flexibility, offset null and frequency compensation controls are included in the HA-2542 pinout. The capabilities of the HA-2542 are ideally suited for high speed coaxial cable driver circuits where low gain and high output drive requirements are necessary. With 5.5MHz full power bandwidth, this amplifier is most suitable for high frequency signal conditioning circuits and pulse video amplifiers. Other applications utilizing the HA-2542 advantages include wideband amplifiers and fast samplehold circuits.
