HT8950A - Voice Modulator

Download the HT8950A datasheet PDF. This datasheet also covers the HT8950 variant, as both devices belong to the same voice modulator family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

Key Features

  • Operating voltage: 2.4V~4.0V.
  • On-chip SRAM.
  • Robot function.
  • Vibrato function.
  • 8kHz sampling rate.
  • 7-step level shifting.
  • 8-bit A/D and D/A converters.
  • LED indicator with voice level.
  • Push button selection or electronic mode.
  • Minimal external components.
  • HT8950: 18-pin DIP package HT8950A: 16-pin DIP package.
