Radiation Hardened, High Speed, Low Power Output Limiting, Closed-Loop-Buffer
Amplifier
Description
Features
The HS-1115RH is a radiation hardened, high speed closed
loop buffer featuring both user programmable gain and
output limiting. QML approved and processed in full
compliance with MIL-PRF-38535. Manufactured in
proprietary, complementary bipolar UHF-1 (DI bonded wafer)
process. The HS-1115RH 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
more flexible product, fewer part types in inventory, and
more efficient use of board space.
Applications
Compatibility with existing op amp pinouts provides flexibility to
upgrade low gain amplifiers, while decreasing component
count. Unlike most buffers, the standard pinout provides an
upgrade path should a higher closed loop gain be needed at a
future date.
