750MHz, Low Distortion Unity Gain,
Closed Loop Buffer
The HFA1110 is a unity gain closed loop buffer that achieves
-3dB bandwidth of 750MHz, while offering excellent video
performance and low distortion. Manufactured on Intersil’s
proprietary complementary bipolar UHF-1 process, the
HFA1110 also offers very fast slew rate, and high output
current. It is one more example of Intersil’s intent to enhance
its leadership position in products for high speed signal
processing applications.
The HFA1110’s settling time of 11ns to 0.1%, low distortion
and ability to drive capacitive loads make it an ideal flash
A/D driver.
The HFA1110 is an enhanced, pin compatible upgrade for
the AD9620, AD9630, CLC110, EL2072, BUF600 and
BUF601.
For buffer applications requiring a standard op amp pinout,
or selectable gain (-1, +1, +2), see the HFA1112 data sheet.
For output limiting see the HFA1113 data sheet.
For military grade product please refer to the HFA1110/883
data sheet.
