Description
The TDA8705AT is a 6-bit high-speed dual analog-to-digital converter (ADC) designed for satellite video and other applications. It can convert two analog input signals into two 6-bit binary-coded digital words at a maximum sampling rate of 80 MHz. The TDA8705AT features TTL-compatible digital inputs and outputs, allowing for easy integration with other systems. It also offers high signal-to-noise ratio over a large analog input frequency range and requires low power dissipation. With its compact size and efficient performance, the TDA8705AT is suitable for various high-speed analog-to-digital conversion applications, including DBS (Digital Broadcast Satellite), QPSK (Quadrature Phase Shift Keying) demodulation, and video processing.
