Preliminary specication
12-bit high-speed Analog-to-Digital
Converter (ADC)
TDA8767
Fig.7 Application diagram (single input mode).
The analog, digital and output supplies should be separated and decoupled.
(1) At power-up a high level clock must be provided within less than 1
s or a pull-up resistor must be connected between CLK and VCCD.
(2) R1, and R2 must be determined in order to obtain a voltage of 2.5 V on VI and VI; see Table 1. To ensure a sufficient analog input stability, the
minimum current into these resistors must be about 1 mA.
(3) Vref must be decoupled to VCCA.
