HS-1115RH
August 1996
Radiation Hardened, High Speed, Low Power
Output Limiting, Closed-Loop-Buffer Ampli鏗乪r
Description
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 鏗俛tness 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 鈥淎pplication Information鈥?text. The result is a
more 鏗俥xible product, fewer part types in inventory, and
more ef鏗乧ient use of board space.
Compatibility with existing op amp pinouts provides 鏗俥xibility to
upgrade low gain ampli鏗乪rs, 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.
