Overview
INTEGRATED CIRCUITS DATA SHEET TDA8702 8-bit video digital-to-analog converter Product specification Supersedes data of April 1993 File under Integrated Circuits, IC02 1996 Aug 23 Philips Semiconductors Product specification 8-bit video digital-to-analog converter FEATURES • 8-bit resolution • Conversion rate up to 30 MHz • TTL input levels • Internal reference voltage generator • Two complementary analog voltage outputs • No deglitching circuit required • Internal input register • Low power dissipation • Internal 75 Ω output load (connected to the analog supply) • Very few external components required.
GENERAL DESCRIPTION APPLICATIONS TDA8702 • High-speed digital-to-analog conversion • Digital TV including: – field progressive scan – line progressive scan • Subscriber TV decoders • Satellite TV decoders • Digital VCRs.
The TDA8702 is an 8-bit Digital-to-Analog Converter (DAC) for video and other applications.
It converts the digital input signal into an analog voltage output at a maximum conversion rate of 30 MHz.
No external reference voltage is required and all digital inputs are TTL compatible.

D0 to D7 connected to VCCD and CLK connected to DGND.
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 Ω.
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).
