Radiation Hardened, High Speed, Low
Power, Current Feedback Video
Operational Amplifier with Output Disable
The HS-1145RH is a high speed, low power current
feedback amplifier built with Intersil’s proprietary
complementary bipolar UHF-1 (DI bonded wafer) process.
These devices are QML approved and are processed and
screened in full compliance with MIL-PRF-38535.
This amplifier features a TTL/CMOS compatible disable
control, pin 8, which when pulled low, reduces the supply
current and forces the output into a high impedance state.
This allows easy implementation of simple, low power video
switching and routing systems. Component and composite
video systems also benefit from this op amp’s excellent gain
flatness, and good differential gain and phase specifications.
Multiplexed A/D applications will also find the HS-1145RH
useful as the A/D driver/multiplexer.
Specifications for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed here must be used when ordering.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-96830. A “hot-link” is provided
on our homepage for downloading.

Driving Capacitive Loads
Capacitive loads, such as an A/D input, or an improperly
terminated transmission line will degrade the amplifier’s
phase margin resulting in frequency response peaking and
possible oscillations. In most cases, the oscillation can be
avoided by placing a resistor (RS) in series with the output
prior to the capacitance.
Figure 1 details starting points for the selection of this
resistor. The points on the curve indicate the RS and CL
combinations for the optimum bandwidth, stability, and
settling time, but experimental fine tuning is recommended.
Picking a point above or to the right of the curve yields an
overdamped response, while points below or left of the curve
indicate areas of underdamped performance.
RS and CL form a low pass network at the output, thus
limiting system bandwidth well below the amplifier bandwidth
of 270MHz (for AV = +1). By decreasing RS as CL increases
(as illustrated in the curves), the maximum bandwidth is
obtained without sacrificing stability. In spite of this, the
bandwidth decreases as the load capacitance increases. For
example, at AV = +1, RS = 62, CL = 40pF, the overall
bandwidth is limited to 180MHz, and bandwidth drops to
75MHz at AV = +1, RS = 8, CL = 400pF.

Evaluation Board
The performance of the HS-1145RH may be evaluated using
the HFA11XX Evaluation Board.
The layout and schematic of the board are shown in Figure 2.
The VH connection may be used to exercise the DISABLE
pin, but note that this connection has no 50termination. To
order evaluation boards (part number HFA11XXEVAL),
please contact your local sales office.
