| HFA1110 Data Sheet February 1999 File Number 2944.7 750MHz, Low Distortion Unity Gain, Closed Loop Buffer The HFA1110 is a unity gain closed loop buffer that achieves -3dB bandwidth of 750MHz, while offering excellent video performance and low distortion. Manufactured on Intersil's proprietary complementary bipolar UHF-1 process, the HFA1110 also offers very fast slew rate, and high output current. It is one more example of Intersil's intent to enhance its leadership position in products for high speed signal processing applications. The HFA1110's settling time of 11ns to 0.1%, low distortion and ability to drive capacitive loads make it an ideal flash A/D driver. The HFA1110 is an enhanced, pin compatible upgrade for the AD9620, AD9630, CLC110, EL2072, BUF600 and BUF601. For buffer applications requiring a standard op amp pinout, or selectable gain (-1, +1, +2), see the HFA1112 data sheet. For output limiting see the HFA1113 data sheet. For military grade product please refer to the HFA1110/883 data sheet.

The use of low inductance components such as chip resistors and chip capacitors is strongly recommended, while a solid ground plane is a must! Attention should be given to decoupling the power supplies. A large value (10F) tantalum in parallel with a small value chip (0.1F) capacitor works well in most cases. Terminated microstrip signal lines are recommended at the input and output of the device. Output capacitance, such as that resulting from an improperly terminated transmission line will degrade the frequency response of the amplifier and may cause oscillations. In most cases, the oscillation can be avoided by placing a resistor (RS) in series with the output. See the "Recommended RS vs Load Capacitance" graph for specific recommendations. An example of a good high frequency layout is the Evaluation Board shown below. 50 +5V 0.1F 10F 1 2 HFA1110 3 IN 50 4 6 5 10F -5V 0.1F 8 7 RS OUT SCHEMATIC DIAGRAM BOTTOM LAYOUT Evaluation Board An evaluation board is available for the HFA1110 (part number HFA1110EVAL).
