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. patibility with existing op amp pinouts provides flexibility to upgrade low gain amplifiers, while decreasing ponent 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 ponent and posite video systems as indicated by the excellent gain flatness, and 0.03%/0.02 Degree Differential Gain/Phase specifications (RL = 150). Its ability to deliver a gain of +2 with no external resistors makes it particularly desirable for applications driving double terminated cables.
