FN3607.6

Dual 350MHz, Low Power Clos ed Loop

Buffer Amplifier

Features

• Differential Gain . . . . . . . . . . . . . . . . . . . . . . . . . . 0.025%

• Differential Phase. . . . . . . . . . . . . . . . . . . . . 0.03 Degrees

The HFA1212 is a dual closed loop Buffer featuring user

programmable gain and high speed performance.

Manufactured on Intersil’s proprietary complementary

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

bandwidth of 350MHz, very fast slew rate, excellent gain

flatness and high output current.

• Wide -3dB Bandwidth (A = +2) . . . . . . . . . . . . . 350MHz

• Very Fast Slew Rate (A = -1) . . . . . . . . . . . . . . 1100V/µs

• Low Supply Current . . . . . . . . . . . . . . . . . . . . 6mA/Buffer

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

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

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.

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

+2 Without Use of External Resistors

• Overdrive Recovery . . . . . . . . . . . . . . . . . . . . . . . . . . 8ns

• Standard Operational Amplifier Pinout

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.
