General Description  
The HT8950/HT8950A are single chip CMOS LSI voice  
modulator ICs which provide seven steps to shift the fre-  
quency of an input voice, producing a dramatic change  
in the output.  
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 sam-  
pling 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.  
The HT8950/HT8950A provide two special effects: Vi-  
brato and Robot. The Vibrato effect is generated by al-  
ternating 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, ei-  
ther ROB or VIB. For the output frequency level shifting,  
the chips provide seven steps which can be selected
