HA-5002
110MHz, High Slew Rate, High Output
Current Buffer
The HA-5002 is a monolithic, wideband, high slew rate, high
output current, buffer amplifier.
Utilizing the advantages of the Intersil D.I. technologies, the
HA-5002 current buffer offers 1300V/
s slew rate with
110MHz of bandwidth. The
200mA output current capability
is enhanced by a 3
output impedance.
The monolithic HA-5002 will replace the hybrid LH0002 with
corresponding performance increases. These characteristics
range from the 3000k
input impedance to the increased
output voltage swing. Monolithic design technologies have
allowed a more precise buffer to be developed with more than
an order of magnitude smaller gain error.
The HA-5002 will provide many present hybrid users with a
higher degree of reliability and at the same time increase
overall circuit performance.
For the military grade product, refer to the HA-5002/883
datasheet, AnswerFAX document #3705.

Schematic Diagram
Application Information
Layout Considerations
The wide bandwidth of the HA-5002 necessitates that high
frequency circuit layout procedures be followed. Failure to
follow these guidelines can result in marginal performance.
Probably the most crucial of the RF/video layout rules is the
use of a ground plane. A ground plane provides isolation and
minimizes distributed circuit capacitance and inductance
which will degrade high frequency performance.
Other considerations are proper power supply bypassing
and keeping the input and output connections as short as
possible which minimizes distributed capacitance and
reduces board space.
Power Supply Decoupling
For optimal device performance, it is recommended that the
positive and negative power supplies be bypassed with
capacitors to ground. Ceramic capacitors ranging in value
from 0.01 to 0.1
F will minimize high frequency variations in
supply voltage, while low frequency bypassing requires
larger valued capacitors since the impedance of the
capacitor is dependent on frequency.
It is also recommended that the bypass capacitors be
connected close to the HA-5002 (preferably directly to the
supply pins).
Operation at Reduced Supply Levels
The HA-5002 can operate at supply voltage levels as low as
5V and lower. Output swing is directly affected as well as
slight reductions in slew rate and bandwidth.
Short Circuit Protection
The output current can be limited by using the following circuit:
Capacitive Loading
The HA-5002 will drive large capacitive loads without oscillation
but peak current limits should not be exceeded. Following the
formula I = Cdv/dt implies that the slew rate or the capacitive
load must be controlled to keep peak current below the
maximum or use the current limiting approach as shown. The
HA-5002 can become unstable with small capacitive loads
(50pF) if certain precautions are not taken. Stability is
enhanced by any one of the following: a source resistance in
series with the input of 50
to 1k
; increasing capacitive load
to 150pF or greater; decreasing C
LOAD
to 20pF or less; adding
an output resistor of 10
to 50
; or adding feedback
capacitance of 50pF or greater. Adding source resistance
generally yields the best results.
