HA-5002
November 1998 File Number 2921.4Data Sheet
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/µs slew rate with 110MHz ofbandwidth. 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 ha ve allowed a more precise bufferto 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.

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 0.1µF 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.

Capacitive Loading
The HA-5002 will drive large capacitive loads without oscillation but peak current limits should not be exceeded. F ollo wing 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 follo wing: a source resistance in series with the input of 50 to 1k; increasing capacitive load to 150pF or greater; decreasing C an output resistor of 10 to 50; or adding feedback capacitance of 50pF or greater. Adding source resistance generally yields the best results.
