TDA8763A Datasheet – 10-bit High Speed Low Power ADC IC
TDA8763A overview
The TDA8763A is a 10-bit high-speed low-power analog-to-digital converter (ADC) for professional video and other applications. It converts the analog input signal into 10-bit binary-coded digital words at a maximum sampling rate of 50 MHz. All digital inputs and outputs are TTL and CMOS compatible, although a low-level sine wave clock input signal is allowed.
The device requires an external source to drive its reference ladder. If the application requires that the reference is driven via internal sources the recommendation is to use the TDA8763.
