Circuit-, IC descriptions and list of abbreviations
A
760 Ohms resistor must be connected from this pin to AGND and is used to
control the amplitudes of the DAC outputs.
Multifunctional input: MPU Port Serial Interface Clock Input.
Multifunctional pin: MPU Port Serial Data Input/Output.
Multifunctional pin. TTL Address Input. This signal sets up the LSB of the MPU
address.
When this pin is tied low the I2C filter is activated which reduces noise on the I2C
interface. When this pin is tied high, the input bandwidth on the I2C lines is
increased.
When this input pin is tied high [Vdd_IO], the ADV7302A/03A interfaces over the
I2C port.
Power supply for digital i/ps and o/ps
