- + DATASHEET HFA1155 FN4863 Rev 1.00 380MHz, SOT-23, Low Power Current Feedback Operational Amplifier September 2004 The HFA1155 is a low power, high-speed op amp and is the Features most recent addition to Intersils HFA1XX5 series of low Low Power 5.5mA power op amps and buffers. Intersil s proprietary complementary bipolar UHF-1 process, coupled with the Low Distortion (10MHz, HD2) -53dBc current feedback architecture deliver superb bandwidth even -3dB Bandwidth 360MHz at very high gains (>250MHz at A = 10). The excellent V High Slew Rate . 1650V/ s video parameters make this amplifier ideal for professional video applications. Fast Settling Time (0.1%) . 38ns Though specified for 5V operation, the HFA1155 operates Excellent Gain Flatness . 0.06dB to 50MHz with single supply voltages as low as 4.5V, and requires only High Output Current . 55mA 1.4mA of I in 5V applications (see Application Information CC section, and Application Note AN9897). Fast Overdrive Recovery . <7ns Operates with 5V Single Supply (See AN9897) Ordering Information PART NUMBER TEMP. PKG. Applications (BRAND) RANGE (C) PACKAGE DWG.
