Description

The HFA1412/883 is a quad closed loop Buffer featuring user programmable gain and high speed performance. Manufactured on Intersil's proprietary complementary bipolar UHF-1 process, this device offers wide -3dB bandwidth of 340MHz, very fast slew rate, excellent gain flatness and high output current.

A unique feature of the HFA1412/883 pinout allows the user to select a voltage gain of +1, -1, or +2, without the use of any external components. Gain selection is accomplished via connections to the inputs, as described in the "Application Information" section. The result is a more flexible product, fewer part types in inventory, and more efficient use of board space.

Compatibility with existing op amp pinouts provides flexibility to HFA1412/883 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.
