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.
FEATURES
• 8-bit resolution
• Conversion rate up to 50 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
• Temperature range
– TDA8712: 0 to 70 °C
– TDF8712: −40 to +85 °C
APPLICATIONS
• 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.
