T62M0002A

tm TE CH T62M0002A T62M0002A Features ! ! ! ! ! ! Operating voltage: 4.5V ~ 5.5V ADM algorithm Low noise ( -88dB typical) Low distortion rate (0.5% typical) Embedded SRAM Automatic reset function Digital Sound Processor Embedded SRAM Description The T62M0002A is an echo/surround effect processor. It is designed for various audio systems including karaoke, television, sound equipment, etc. The chip consists of a built-in pre-amplifier, VCO or Voltage control OSC, Embedded SRAM, A/D and D/A converters as well as delay time control logic. Its built-In reply to 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. ! Package type: 16-pin DIP/SOP Part Number Examples Part NO.
