Dual, High Speed, Low Power,

Video Closed Loop Buffer

Features

Description

• This Circuit is Processed in Accordance to MIL-STD- The HFA1212/883 is a dual closed loop Buffer featuring user

883 and is Fully Conformant Under the Provisions of programmable gain and high speed performance. Manufac-

Paragraph 1.2.1.

tured 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.

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

or +2 Without Use of External Resistors

• Standard Operational Ampliﬁer Pinout

A unique feature of the pinout allows the user to select a volt-

age gain of +1, -1, or +2, without the use of any external

components. Gain selection is accomplished via connec-

tions to the inputs, as described in the “Application Informa-

tion” section. The result is a more ﬂexible product, fewer part

types in inventory, and more efﬁcient use of board space.

• Low Supply Current. . . . . . . . . . 5.9mA/Op Amp (Typ)

• Excellent Gain Accuracy. . . . . . . . . . . . . .0.99V/V (Typ)

• Wide -3dB Bandwidth . . . . . . . . . . . . . . . 340MHz (Typ)

• Fast Slew Rate . . . . . . . . . . . . . . . . . . . . 1155V/µs (Typ)

• High Input Impedance . . . . . . . . . . . . . . . . . . 1MΩ (Typ)

• Excellent Gain Flatness (to 50MHz) . . . . ±0.02dB (Typ)

• Fast Overdrive Recovery. . . . . . . . . . . . . . . <10ns (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.
