850MHz, Low Distortion Programmable

Gain Buffer Amplifiers

The HFA1112 is a closed loop Buffer featuring user

programmable gain and ultra high speed performance.

Manufactured on Intersil’s proprietary complementary

bipolar UHF-1 process, these devices offer a wide -3dB

bandwidth of 850MHz, very fast slew rate, excellent gain

flatness, low distortion and high output current.

A unique feature of the 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 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.

This amplifier is available with programmable output limiting

as the HFA1113. For applications requiring a standard buffer

pinout, please refer to the HFA1110 data sheet.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets;

molding compounds/die attach materials and 100% matte tin plate termination finish,

which are RoHS compliant and compatible with both SnPb and Pb-free soldering

operations. Intersil Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
