processor’s convenience, at any clock rate from 0MHz
to 2MHz. SSTRB goes low at the start of the conversion
and then goes high when the conversion is complete.
SSTRB is low for a maximum of 7.5s (SHDN = FLOAT),
during which time SCLK should remain low for best
noise performance.
An internal register stores data when the conversion is
in progress. SCLK clocks the data out of this register at
any time after the conversion is complete. After SSTRB
goes high, the next falling clock edge produces the
MSB of the conversion at DOUT, followed by the
remaining bits in MSB-first format (Figure 9). CS does
not need to be held low once a conversion is started.
Pulling CS high prevents data from being clocked into
the MAX146/MAX147 and three-states DOUT, but it
does not adversely affect an internal clock mode
conversion already in progress. When internal clock
mode is selected, SSTRB does not go into a high-
impedance state when CS goes high.
Figure 10 shows the SSTRB timing in internal clock
mode. In this mode, data can be shifted in and out of
the MAX146/MAX147 at clock rates exceeding 2.0MHz
if the minimum acquisition time (tACQ) is kept above
1.5s.
