HT8970 Voice Echo Features · Operating voltage: 4.5V~5.5V · Built-in 20Kb SRAM · ADM algorithm · Automatic reset function · Low noise - Echo mode: -85dB - Surround mode: -90dB · 16-pin DIP/SOP package Applications · Television · Video disc player · Karaoke systems · 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 components and make it easy to adjust the delay time.
