During Shutdown mode, on the falling edge of CS, the
conversion process begins. During this process, the
internal oscillator clocks the delta-sigma modulator and
the SINC filter until a conversion is complete. This
conversion time is t

settled completely and there is no latency involved with
the digital SINC filter of the MCP3550/1/3.
The two modes of conversion for the MCP3550/1/3
devices are Single Conversion and Continuous
Conversion. In Single Conversion mode, a consecutive
conversion will not automatically begin. Instead, after a
single conversion is complete and all four filters have
settled, the device puts the data into the output register
and enters shutdown.

In Continuous Conversion mode, a consecutive
conversion will be automatic. In this mode, the device
is continuously converting, independent of the serial
interface. The most recent conversion data will always
be available in the Output register.
When the device exits Shutdown, there is an internal
power-up delay that must be observed.
