50 W MIN. AF POWER AMPLIFIER OUTPUT STAGE (DPP) ® INTEGRATED EMITTER RESISTOR SANYO THICK FILM HYBRID INTEGRATED CIRCUIT
FEATURES
- Does not require externally connected emitter resistors. + Values of emitter resistors have carefully been reviewed to provide superior characteristics. a. Better supply voltage utilization permits designing power supply voltages that are +0.7 V (for R= 482) lower than those required for previous DPP models. b. Maximum allowable power consumption for each resistor is 5 W or higher, permitting accommodation for all loads. c. Peak allowable current is 18 A or more, providing an ample margin even for peak currents under when short circuited or similar emergencies. d. In particular, maximum outputs 4Q have been enormously improved. + Use of emitter resistors facilitates meeting deferent safety standards and designing PCBs. + Mutual interferences in the high-frequency range caused by layout of externally connected emitter resistors no longer exist. This facilitates lower distortion factors. . + Pins are used for emitter resistor output terminals that were not connected in previous DPPs. All other terminals remain unchanged; there is no need for major circuit board changes.
