The HFA1155 is a low power, high-speed op amp and is the
most recent addition to Intersil’s HFA1XX5 series of low
power op amps and buffers. Intersil's proprietary
complementary bipolar UHF-1 process, coupled with the
current feedback architecture deliver superb bandwidth even
at very high gains (>250MHz at A = 10). The excellent
V
video parameters make this amplifier ideal for professional
video applications.
Though specified for ±5V operation, the HFA1155 operates
with single supply voltages as low as 4.5V, and requires only
1.4mA of I
in 5V applications (see Application Information
CC
section, and Application Note AN9897).
Applications
For a lower distortion, higher bandwidth amplifier in a SOT-
23 package, please refer to the HFA1150 data sheet.
