Product Details

The AD1970 is an analog or digital in, analog out TV Stereo Digital Audio Processor with programmable MTS (BTSC) encoder which includes pilot-tone generation and sub-carrier mixing functions. The stereo ADC provides the means for digitization of the analog baseband audio signal. A built-in high performance DAC is provided to output the BTSC base-band composite signal. The output of the AD1970 can be connected with minimal external circuitry to the input of a 4.5 MHz aural FM modulator.

In addition to the digital BTSC encoder, the AD1970 includes a stereo image enhancement function, Phat Stereo, to increase the sense of spaciousness available from closely spaced TV loudspeakers. A dialog enhancement algorithm solves the problem of playing wide dynamic range sources over limited-performance TV speakers and amplifiers. An I2C port allows control of the AD1970’s registers and parameters.
