Preliminary specification
12-bit high-speed Analog-to-Digital
Converter (ADC)
TDA8767
APPLICATION INFORMATION
Fig.6 Application diagram (differential 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
μ
s or a pull-up resistor must be connected between CLK and V
CCD
.
(2) R1, and R2 must be determined in order to obtain a middle voltage of 2.5 V; see Table 1. To ensure a sufficient analog input stability, the minimum
current into these resistors must be about 1 mA.
(3) V
ref
must be decoupled to V
CCA
.
