HT8950/HT8950A -- Voice Modulator

The HT8950 HT8950A are single chip CMOS LSI voice Modulator ICs which provide seven steps to shift the frequency of an input voice, producing a dramatic change in the output. The HT8950 HT8950A provide two special effects: Vibrato and Robot. The Vibrato effect is generated by alternating the frequency of an input signal up and down at a rate of 8Hz. The Robot function, on the other hand, converts an input voice into a Robot voice. Both effects CAN be selected depending on which pin is triggered, either ROB or VIB. For the output frequency level shifting, the chips provide seven steps which CAN be selected from the two groups of pins namely, SW0, SW1 and SW2 for electronic direct selection and ROB, TGD, TGU and VIB for push button selection. The HT8950 HT8950A include a built-in Microphone Amplifier with an internal bias, an 8-bit A/D converter a built-in SRAM as well as a current output type 8-bit D/A Converter The 8-bit A/D and D/A Converters with a sampling rate of 8kHz ensures a high quality and high S/N ratio output voice. The chips provide an LED indicator which flashes in accordance with the volume of the input voices.
