Philips Semiconductors
Preliminary specication
12-bit high-speed Analog-to-Digital
Converter (ADC)
TDA8768
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
Note
1. The supply voltages VCCA, VCCD and VCCO may have any value between 0.3 V and +7.0 V provided that the supply
voltage differences
VCC are respected.
HANDLING
Inputs and outputs are protected against electrostatic discharges in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling integrated circuits.
