Technical content

The AN5138NK is an integrated circuit designed for video-IF and audio-IF processing circuits, in color TV and VCR. n Features

  • By adopting built-in VCO PLL-type video-detector cir- cuit, the high preformance IC-detector system can be realized for sound multiplex and tele-text broadcasting.
  • Quadrature sound FM detector built-in.
  • Frequency characteristics compensation pin (Pin20) VCR-switch pin (Pin5)
  • Sound-output level-adjustment pin (Pin25) ICs for TV AN5138NK Video IF Amplifier, PLL Detector, AGC, AFC, SIF IC for Color TV 26.7–0.3 8.4–0.3 – 0.05 4.8–0.25 1.05–0.25 3.05–0.25 1.778 0.5–0.1 0.9–0.25 Unit : mm 28-Pin Shrunk DIL Plastic Package 25 24 23 22 21 20 19 18 1110987654 Audio Level Adj.
