Conversion data digital Output pins. D0 is the LSB, D7 is
the MSB. Valid data is output just after the rising edge of the
CLK input. These pins are enabled by bringing the OE pin
low.
Positive digital supply pin. Connect to a clean voltage
source of +5V. AV
source and be separately bypassed with a 10µF capacitor
and a 0.1µF ceramic chip capacitor. See Section 3.0 for
more information.
This digital supply pin supplies power for the digital output
drivers. This pin should be connected to a supply source in
the range of 2.5V to the Pin 13 potential.
The ground return for the digital supply. AV
should be connected together close to the ADC1175.
Positive analog supply pin. Connected to a quiet voltage
source of +5V. AV
source and be separately bypassed with a 10 µF capacitor
and a 0.1 µF ceramic chip capacitor. See Section 3.0 for
more information.
The ground return for the analog supply. AV
should be connected together close to the ADC1175
package.
