Output Limiting, Closed-Loop-Buffer Amplifier
August 1996
Features
Description
• Electrically Screened to SMD 5962F9678501VPA
• MIL-PRF-38535 Class V Compliant
The HS-1115RH is a radiation hardened, high speed closed
loop buffer featuring both user programmable gain and out-
put limiting. They are QML approved and processed in full
compliance with MIL-PRF-38535. Manufactured in propri-
etary, complementary bipolar UHF-1 (DI bonded wafer) pro-
cess, the HS-1115RH also offers a wide -3dB bandwidth of
225MHz, very fast slew rate, excellent gain flatness and high
output current.

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 HS-1115RH 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

upgrade low gain amplifiers, while decreasing component

upgrade path should a higher closed loop gain be needed at a
future date.
