The HFA1100 is a high-speed, wideband, fast settling current feedback amplifier built with Intersil's proprietary complementary bipolar UHF-1 process. It operates with single supply voltages as low as 4. 5V (see Application Information section). The HFA1100 is a basic op amp with uncommitted pins 1, 5, and 8. This device offers a significant performance improvement over the AD811, AD9617/18, the CLC400-409, and the EL2070, EL2073, EL2030.

The HFA1130 is a High-Speed wideband current feedback amplifier featuring programmable output limits. Built with Intersil’s proprietary complementary bipolar UHF-1 process, it is the fastest monolithic amplifier available from any semiconductor manufacturer. This amplifier is the ideal choice for high frequency applications requiring output limiting, especially those needing ultra fast overdrive recovery times. The output limiting function allows the designer to set the maximum positive and negative output levels, thereby protecting later stages from damage or input saturation. The sub-nanosecond overdrive recovery time quickly returns the amplifier to linear operation, following an overdrive condition. The HFA1130 offers significant performance improvements over the CLC500/501/502.

The HFA1412 is a quad closed loop Buffer featuring user programmable gain and high speed video performance. A unique feature of the HFA1412's pinout allows the user to select a voltage gain of +1, -1, or +2 (see the Application Information section). The on-chip gain setting resistors eliminate eight external resistors, thus saving board space or freeing up space for termination resistors. The on-chip feedback resistor is preset at the optimum value, and also eliminates worries about parasitic feedback capacitance. Additionally, the capacitance sensitive summing node is buried inside the package where it is unaffected by PCB parasitics. Compatibility with existing op amp pinouts provides flexibility to upgrade low gain amplifiers, while decreasing component count. Unlike most buffers, the standard pinout provides an upgrade path should a higher closed loop gain be needed at a future date. The HFA1412 is an excellent choice for component and composite video systems as indicated by the excellent gain flatness, and 0. 03%/0. 02 Degree Differential Gain/Phase specifications (RL = 150Ω). Its ability to deliver a gain of +2 with no external resistors makes it particularly desirable for applications driving double terminated cables.
