1 / 9 page  HT8970 Voice Echo 1 March 14, 2000 Features · Operating voltage: 4.5V~5.5V · ADM algorithm · Low noise - Echo mode:-85dB - Surround mode:-90dB · Low distortion rate - Echo mode: 1% - Surround mode: 0.2% · Built-in 20Kb SRAM · Automatic reset function · Package type: 16-pin DIP/SOP Applications · Television · Karaoke systems · Video disc player · Sound equipments General Description The HT8970 is an echo/surround effect processor. It is designed for various audio systems including karaoke, television, sound equipments, etc. The chip consists of a built-in pre-amplifier, VCO or Voltage Control OSC, 20Kb SRAM, A/D and D/A converters as well as delay time control logic. Its built-in 20Kb SRAM can generate delay time effect and can control the delay time value through the external VCO resistor. The VCO circuit can reduce external compo- nents and make it easy to adjust the delay time. |
