Description
General part information
HFA1412 Series
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. For Military product, refer to the HFA1412/883 data sheet.
