HFA1155IB中文资料Intersil数据手册PDF规格书

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. Intersils 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.
