AD7610
Power Sequencing
The AD7610 is independent of power supply sequencing and is
very insensitive to power supply variations on AVDD over a wide
frequency range as shown in Figure 31.

Power Dissipation vs. Throughput
The AD7610 automatically reduces its power consumption at
the end of each conversion phase. During the acquisition phase,
the operating currents are very low, which allows a significant
power savings when the conversion rate is reduced (see Figure 32).
This feature makes the AD7610 ideal for very low power, battery-
operated applications.
It should be noted that the digital interface remains active even
during the acquisition phase. To reduce the operating digital supply
currents even further, drive the digital inputs close to the power
rails (that is, OVDD and OGND).

Power Down
Setting PD = high powers down the AD7610, thus reducing
supply currents to their minimums as shown in Figure 23. When
the ADC is in power down, the current conversion (if any) is
completed and the digital bus remains active. To further reduce
the digital supply currents, drive the inputs to OVDD or OGND.
Power down can also be programmed with the configuration
register. See the Software Configuration section for details. Note
that when using the configuration register, the PD input is a
don’t care and should be tied to either high or low.
CONVERSION CONTROL
The AD7610 is controlled by the CNVST input. A falling edge
on CNVST is all that is necessary to initiate a conversion. Detailed
timing diagrams of the conversion process are shown in Figure 33.
Once initiated, it cannot be restarted or aborted, even by the
power-down input, PD, until the conversion is complete. The
CNVST signal operates independently of CS and RD signals.

Figure 33. Basic Conversion Timing
Although CNVST is a digital signal, it should be designed with
special care with fast, clean edges, and levels with minimum
overshoot, undershoot, or ringing.
The CNVST trace should be shielded with ground and a low value
(such as 50 Ω) serial resistor termination should be added close
to the output of the component that drives this line.
For applications where SNR is critical, the CNVST signal should
have very low jitter. This can be achieved by using a dedicated
oscillator for CNVST generation, or by clocking CNVST with a
high frequency, low jitter clock, as shown in Figure 27.
