FN2992.8

850MHz, Low Distortion Programmable

Gain Buffer Amplifiers

Features

• User Programmable for Closed-Loop Gains of +1, -1 or +2

without Use of External Resistors

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.

• Wide -3dB Bandwidth. . . . . . . . . . . . . . . . . . . . . . 850MHz

• Very Fast Slew Rate. . . . . . . . . . . . . . . . . . . . . . 2400V/µs

• Fast Settling Time (0.1%). . . . . . . . . . . . . . . . . . . . . 11ns

• High Output Current. . . . . . . . . . . . . . . . . . . . . . . . . 60mA

• Excellent Gain Accuracy . . . . . . . . . . . . . . . . . . . 0.99V/V

• Overdrive Recovery . . . . . . . . . . . . . . . . . . . . . . . . <10ns

• Standard Operational Amplifier Pinout

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.

• Pb-Free Plus Anneal Available (RoHS Compliant)

Applications

• RF/IF Processors

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.

• Driving Flash A/D Converters

• High-Speed Communications

• Impedance Transformation

• Line Driving

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.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
