VERY LOW CURRENT ABSORPTION 3 STAGE IF GAIN CONTROLLED AMPLIFIER SYNCHRONOUS VIDEO DEMODULATOR WHITE SPOT AND NOISE INVERTER AGC CIRCUIT WITH NOISE GATING TUNER AGC OUTPUT FOR PNP TUNERS FM DETECTOR AF AMPLIFIER WITH DC VOLUME CONTROL AFC 2 VPP ON VIDEO OUTPUT
DIP20 (Plastic Package)
DESCRIPTION The TDA8213 is a monolithic integrated circuit in DIP20 package for colour and black & white television receivers using PNP tuners. It is intended to operate with a negatively modulated vision carrier and frequency modulated sound carrier. Used with TDA8214/15 (H/V deflection circuit) and TDA8217 (Pal decoder and video processor), this IC permits a complete low-cost solution for PAL applications. PIN CONNECTIONS
