Two control words are necessary to enable the ADC.
The first control word brings the ADC out of shutdown,
and sets the T/H in acquisition mode. The second con-
trol word initiates the conversion.
Bit 2 (E2) controls the reference. A logic “1” enables
the reference, a logic “0” disables the reference, further
reducing power consumption.
Power Supply Bypassing and Layout
For best performance, use printed circuit boards. Wire-
wrap boards are not recommended. Board layout
should ensure that digital and analog signal lines are
separated from each other. Do not run analog and digi-
tal (especially clock) lines parallel to one another or run
digital lines underneath the device.
Figure 10 shows the recommended system-ground
connections. A single-point analog ground (star-ground
point) should be established at the device ground.
Connect all analog grounds to the star ground. No digi-
tal-system ground should be connected to this point.
The ground return to the power supply for the star
ground should be connected to this point. The ground
return to the power supply for the star ground should
be low impedance and as short as possible for noise-
free operation. High-frequency noise in the VDD power
supply may affect device performance. Bypass the
supply to the star ground with 0.1F and 1F capaci-
tors close to the device. Minimize capacitor lead
lengths for best supply-noise rejection. If the power
supply is very noisy, connect a 10
resistor in series
with VDD to form a lowpass filter.
