HFA1155IB96

HFA1155 TM Data Sheet June 2000 File Number 4863 380MHz, SOT-23, Low Power Current Feedback Operational Amplifier 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 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 SOT23 package, please refer to the HFA1150 data sheet.
