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 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.

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.

... Input Unity Gain Considerations Unity gain selection is accomplished by ﬂoating the -Input of the HS-1115RH. Anything that tends to short the -Input to GND, such as stray capacitance at high frequencies, will cause the ampliﬁer gain to increase toward a gain of +2. The result is excessive high frequency peaking, and possible instability ...

... Evaluation Board The performance of the HS-1115RH may be evaluated using the HFA11XX Evaluation Board, slightly modiﬁed as follows: 1. Remove the 500 feedback resistor (R2), and leave the connection open For evaluation, remove the 500 gain setting V resistor (R1), and leave pin 2 floating. ...
