Technical content

The AN7062N is a high voltage integrated circuit de- signed for pre-driver of 60W-class Hi-Fi audio amp. Stereo operation is enabled due to two amplifiers built-in. n Features

  • High voltage
  • Low noise : Vni = 2.5µV (typ.)
  • Low distortion : THD = 0.003% (typ.)
  • Good channel separation
  • Wide operating supply voltage range AN7062N High Voltage Input Amplifier Circuit for Hi-Fi Power Amplifier 3 ~ 15˚ 7.62–0.25 0.3 + 0.1 – 0.25 3.8–0.25 (3.45) 0.51min. 2.54 1.2–0.25 0.5–0.1 Unit : mm 6.3–0.25 21.7–0.3 9 10 18-Lead DIP Package (DIP018-P-300E) n Block Diagram 4 5 6 7 8 9 11 12 13 14 15 1 18 10 GND –V CC1 +V CC –V CC2 (L.F.B)(L.F.B) Current Mirror Cascade Bootstrap Emitter Follower Differential Amplifier Current Mirror Cascade Bootstrap Differential Amplifier Emitter Follower Current Mirror Current Source
