Product specification

8-bit high-speed analog-to-digital converter

TDA8714

APPLICATION INFORMATION

Fig.14 Application diagram.

The analog and digital supplies should be separated and decoupled.

The external voltage generator must be built such that a good supply voltage ripple rejection is achieved with respect to the LSB value.

(2) Pin 5 should be connected to AGND; pins 3 and 10 to DGND in order to prevent noise influence.
