... Satellite TV decoders Digital VCRs Industrial and automotive. GENERAL DESCRIPTION The TDA8712 and TDF8712 are 8-bit digital-to-analog converters (DACs) for video and other applications. They convert the digital input signal into an analog voltage output at a maximum conversion rate of 50 MHz. No external reference voltage is required and all digital inputs are TTL compatible ...
