The HPR4XX Series uses advanced circuit design and packaging technology to realize superior reliability and performance. A 170kHz push-pull oscillator is used in the input stage. The HPR4XX Series reduces beat-frequency oscillation problems when used with high frequency isolation amplifiers. Reduced parts count and high efficiency add to the reliability of the HPR4XX Series.
The high efficiency of the HPR4XX Series means less internal power dissipation, as low as 190mW. With less heat to dissipate the HPR4XX Series can operate at higher temperatures with no degradation of reliable operation. In addition, the high efficiency of the HPR4XX Series means the series is able to offer greater than 10 W/inch3 of output power density. Operation down to no load
will not impact the reliability of the series, although this product has a >1mA minimum load for specifications purposes. The HPR4XX Series provides high isolation in a very small package. The use of surface mounted devices and manufacturing technologies makes it possible to offer premium performance and low cost.
SPECIFICATIONS All specifications are typical at TA = +25°……
