HFA1115/883 TM High Speed, Low Power, Output Limiting Closed Loop Buffer Amplifier July 1994 Features Description • This Circuit is Processed in Accordance to MIL-STD883 and is Fully Conformant Under the Provisions of Paragraph 1.2.1. The HFA1115/883 is a high speed closed loop Buffer featuring both user programmable gain and output limiting. Manufactured in Intersil’ proprietary complementary bipolar UHF-1 process, the HFA1115/883 also offers a wide -3dB bandwidth of 225MHz, very fast slew rate, excellent gain flatness and high output current. • User Programmable Output Voltage Limiting • User Programmable For Closed-Loop Gains of +1, -1 or +2 Without Use of External Resistors This buffer is the ideal choice for high frequency applications requiring output limiting, especially those needing ultra fast overload recovery times. The limiting function allows the designer to set the maximum positive and negative output levels, thereby protecting later stages from damage or input saturation. The HFA1115/883 also allows for voltage gains of +2, +1, and -1, without the use of external resistors. Gain selection is accomplished via connections to the inputs, as described in the “Application Information” text. The result is a more flexible product, fewer part types in inventory, and more efficient use of board space. • Standard Operational Amplifier Pinout • Fast Overdrive Recovery . . . . . . . . . . . . . . . <1ns (Typ) • Low Supply Current. . . . . . . . . . . . . . . . . . 6.9mA (Typ) • Excellent Gain Accuracy . . . . . . . . . . . . . . 0.99V/V (Typ) • Wide -3dB Bandwidth . . . . . . . . . . . . . . . 225MHz (Typ) • Fast Slew Rate . . . . . . . . . . . . . . . . . . . . 1135V/µs (Typ) • High Input Impedance . . . . . . . . . . . . . . . . . . 1MΩ (Typ) • Excellent Gain Flatness (to 50MHz) . . . . . ±0.1dB (Typ) Compatibility with existing op amp pinouts provides flexibility to upgrade low gain amplifiers, while decreasing component count.
