· High-speed digital-to-analog conversion · Digital TV including: field progressive scan line progressive scan · Subscriber TV decoders · 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.

2. The analog output voltages (VOUT and VOUT) are negative with respect to VCCA (see Table 1). The output resistance between VCCA and each of these outputs is typically 75 . 3. The -3 dB analog output bandwidth is determined by real time analysis of the output transient at a maximum input code transition (code 0 to 255).
