General Description
The HT8950 is a single chip CMOS LSI voice
modulator. It provides 7 steps to shift the fre-
quency of an input voice, producing a dramati-
cal change in the output.
The HT8950 provides two special effects: Vi-
brato 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 func-
tion, 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 chip provides 7 steps which can be
selected from the two groups of pins namely,
SW0, SW1 and SW2 for electronic direct selec-
tion and ROB, TGD, TGU and VIB for push
button selection.
The HT8950 includes a built-in microphone am-
plifier with an internal bias, an 8-bit A/D con-
verter, 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 chip provides an LE D indica-
tor which flashes with the volume of the input
voices. It is offered in a 16-pin or 18-pin DIP
package.
