Description

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 AV = 10). The excellent video parameters make this HFA1155 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 ICC in 5V applications (see Application Information section, and Application Note AN9897). For a lower distortion, higher bandwidth amplifier in a SOT-23 package, please refer to the HFA1150 data sheet.
