Voice Modulator

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. Features Operating voltage: 2.4V~4.0V On-chip SRAM Robot function Vibrato function

ISO-CMOS ST-BUS??FAMILY Data Codec

Description The MT8950 is a coder/decoder which uses the Transition Encoded Modulation (TEM) technique for encoding/decoding low speed data to and from a 56/64 kbps channel (equivalent to PCM Voice). The coding and decoding scheme is transparent and can accept either synchronous or asynchronous d

Varactor-Tuned Oscillators

Description HP VTO-8000 Series oscillators use a silicon transistor chip as a negative resistance oscillator. The oscillation frequency is determined by a silicon abrupt varactor diode acting as a voltage-variable capacitor in a thin-film micro stripline resonator. This provides extremely fast

ADC WITH MICROPHONE INPUT AND PROGRAMMABLE DIGITAL FILTERS

DESCRIPTION The WM8950 is a low power, high quality mono ADC designed for portable applications such as Digital Still Camera, Digital Voice Recorder or games console accessories. The device integrates support for a differential or single ended mic. External component requirements
