ADC optimised for compatibility and easy design-in

The TDA8765 from NXP Semiconductors is a 10-bit, high-speed ADC offering TTL- and CMOS-compatible inputs as well as CMOS-compatible outputs for easy integration.

Analogue input capacitance of 2pF permits sampling at up to 55MHz without requiring a buffer amplifier. The ADC also provides a differential clock input compatible with Positive Emitter- Coupled Logic (PECL) signalling, enabling high-speed operation from a logic-derived clock signal. A sine-wave clock signal can also be used.

Integrated features of the TDA8765 include the sample-and-hold amplifier as well as a voltage-controlled regulator. A differential analogue input is also provided, which allows the ADC to be implemented directly in a wide variety of high-speed circuits and applications.

 

FEATURES 325mW typical power dissipation -3dB bandwidth of 200MHz External amplitude-range control Binary or twos-complement outputs 5V operating voltage

APPLICATIONS Digital video manipulation High-Definition TV (HDTV) Imaging cameras and scanners Medical imaging Wired and wireless communications
