This device features an outstanding set of AC parameters augmented by excellent output drive capability providing for suitable application in both high speed and high output drive circuits. Primarily intended to be used in balanced 50Ω and 75Ω coaxial cable systems as a driver, the HA-2542 could also be used as a power booster in audio systems as well as a power amp in power supply circuits. This device would also be suitable as a small DC motor driver. The applications shown in Figures 2 through Figure 4 demonstrate the HA-2542 at gains of +100 and +2 and as a video cable driver for small signals. Power Dissipation Considerations 5 At high output currents, especially with the PDIP package, care must be taken to ensure that the Maximum Junction Temperature (TJ, see “Absolute Maximum Ratings” table) is not exceeded. As an example consider the HA-2542 in the PDIP package, with a required output current of 20mA at VOUT = 5V. The power dissipation is the quiescent power (1.2W = 30V x 40mA) plus the power dissipated in the output stage (POUT = 200mW = 20mA x (15V - 5V)), or a total of 1.4W. The thermal resistance (θJA) of the PDIP package is 100oC/W, which increases the junction temperature by 140oC over the ambient temperature (TA). Remaining below TJMAX requires that TA be restricted to ≤ 10oC (150oC - 140oC). Heatsinking would be required for operation at ambient temperatures greater than 10oC. MAXIMUM TA WITHOUT HEATSINK (oC) HA-2542 120 possible: 4) placing power supply decoupling capacitors from device supply pins to ground. VOUT = ±5V VS = ±15V 100 Frequency Compensation The HA-2542 may be externally compensated with a single capacitor to ground. This provides the user the additional flexibility in tailoring the frequency response of the amplifier. A guideline to the response is demonstrated on the typical performance curve showing the normalized AC parameters versus compensation capacitance. It is suggested that the user check and tailor the accurate compensation value for each application. As shown additional phase margin is achieved at the loss of slew rate and bandwidth. 80 60 40 20 0 PDIP 0 5 10 15 20 25 30 35 40 45 OUTPUT CURRENT (100% DUTY CYCLE, mA) 50 FIGURE 1. MAXIMUM OPERATING TEMPERATURE vs OUTPUT CURRENT Allowable output power can be increased by decreasing the quiescent dissipation via lower supply voltages. For more information please refer to Application Note AN556, “Thermal Safe Operating Areas for High Current Op Amps”. Prototyping Guidelines For best overall performance in any application, it is recommended that high frequency layout techniques be used. This should include: 1) mounting the device through a ground plane: 2) connecting unused pins (NC) to the ground: 3) mounting feedback components on Teflon standoffs and or locating these components as close to the device as For example, for a voltage gain of +2 (or -1) and a load of 500pF/2kΩ, 20pF is needed for compensation to give a small signal bandwidth of 30MHz with 40o of phase margin. If a full power output voltage of ±10V is needed, this same configuration will provide a bandwidth of 5MHz and a slew rate of 200V/µs. If maximum bandwidth is desired and no compensation is needed, care must be given to minimize parasitic capacitance at the compensation pin. In some cases where minimum gain applications are desired, bending up or totally removing this pin may be the solution. In this case, care must also be given to minimize load capacitance. For wideband positive unity gain applications, the HA-2542 can also be over-compensated with capacitance greater than 30pF to achieve bandwidths of around 25MHz. This over-compensation will also improve capacitive load handling or lower the noise bandwidth. This versatility along with the ±100mA output current makes the HA-2542 an excellent high speed driver for many power applications.
