描述 Description

The HFA1113/883 is a closed loop buffer featuring a high degree of gain accuracy, wide bandwidth, low distortion, and programmable output limiting. This buffer is the ideal choice for high frequency applications requiring output limiting, especially those needing ultra fast overdrive recovery times. The output limiting function allows the designer to set the maximum positive and negative output levels, thereby protecting later stages from damage or input saturation. The sub-nanosecond overdrive recovery time quickly returns the amplifier to linear operation following an overdrive condition.
