DATASHEET HA-52 MHz, High Slew Rate, High Output Current Buffer The HA-52 is a monolithic, wideband, high slew rate, high output current, buffer amplifier. Utilizing the advantages of the Intersil D.I. technologies, the HA-52 current buffer offers V/ s slew rate with MHz of bandwidth. The 2mA output current capability is enhanced by a output impedance. The monolithic HA-52 will replace the hybrid LH2 with corresponding performance increases. These characteristics range from the k 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-52 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-52/ datasheet. Features FN292 Rev 2.

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. to. 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-52 (preferably directly to the supply pins). Operation at Reduced Supply Levels The HA-52 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: V+ I MAX = 2mA R LIM ------------------------- V+ V- = = ------------------------- I (CONTUOUS) MAX I MAX Capacitive Loading The HA-52 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-52 can become unstable with small capacitive loads (5pF) if certain precautions are not taken. Stability is enhanced by any one of the following: a source resistance in series with the input of 5 to k ; increasing capacitive load to 5pF or greater; decreasing C LOAD to 2pF or less; adding an output resistor of to 5 ; or adding feedback capacitance of 5pF or greater. Adding source resistance generally yields the best results. V - V- R LIM V 2 + V 2 - R LIM FN292 Rev 2. Page 5 of 2
