Description

The HFA1110/883 is a unity gain, closed loop buffer which
achieves a high degree of gain accuracy, wide bandwidth,
and low distortion. Manufactured on Intersil’s proprietary
complementary bipolar UHF-1 process, the HFA1110/883
also offers very fast slew rates, and high output current.

Component and composite video systems will also benefit
from this buffer’s performance, as indicated by the excellent
gain flatness, and 0.04%/0.025 Degree Differential
Gain/Phase specifications (R

For buffer applications desiring a standard op amp pinout, or
selectable gain (-1, +1, +2), please refer to the HFA1112/883
and HFA1113/883 (featuring programmable output clamps)
datasheets.
