HFA1115/883

High Speed, Low Power, Output Limiting

Closed Loop Buffer Amplifier

July 1994

Features

Description

• This Circuit is Processed in Accordance to MIL-STD-

883 and is Fully Conformant Under the Provisions of

Paragraph 1.2.1.

The HFA1115/883 is a high speed closed loop Buffer featur-

ing both user programmable gain and output limiting. Manu-

factured in Intersil’ proprietary complementary bipolar UHF-1

process, the HFA1115/883 also offers a wide -3dB band-

width of 225MHz, very fast slew rate, excellent gain flatness

and high output current.

• User Programmable Output Voltage Limiting

• User Programmable For Closed-Loop Gains of +1, -1

or +2 Without Use of External Resistors

This buffer is the ideal choice for high frequency applications

requiring output limiting, especially those needing ultra fast

overload recovery times. The limiting function allows the

designer to set the maximum positive and negative output lev-

els, thereby protecting later stages from damage or input satu-

ration. The HFA1115/883 also allows for voltage gains of +2,

+1, and -1, without the use of external resistors. Gain selec-

tion is accomplished via connections to the inputs, as

described in the “Application Information” text. The result is a

more flexible product, fewer part types in inventory, and more

efficient use of board space.

• Excellent Gain Flatness (to 50MHz) . . . . . ±0.1dB (Typ)

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.

1. Output is short circuit protected to ground. Brief short circuits to ground will not degrade reliability, however continuous (100% duty cycle)

output current must not exceed 30mA for maximum reliability.
