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.
