Input Data Format
Input data (configuration and conversion bytes) are
clocked into the MAX1298/MAX1299 at DIN on the ris-
ing edge of SCLK when CS is low. The start bit (MSB)
of an input data byte is the first logic 1 bit that arrives:
After CS falls,
OR
after receipt of a complete configuration byte with no
conversion in progress,
OR
after 16 bits have been clocked onto DOUT following a
conversion.
Output Data Format
Output data from the MAX1298/MAX1299 are clocked
onto DOUT on the falling edge of SCLK in the form of two
8-bit words, MSB first (Table 1). For temperature conver-
sions, the output is 12-bit binary (D10S0) padded with 2
leading extraneous bits and two trailing zeros. For volt-
age conversions, the output is 12-bit twos-complement
binary (D11D0) with 1 sub-bit and two trailing zeros.
Figure 5 shows the bipolar transfer function.
Performing a Conversion
On power-up, the MAX1298/MAX1299 defaults to shut-
down mode. Start a conversion by transferring a configu-
ration byte and a conversion byte into DIN with the
control formats shown in Tables 2 and 3, respectively.
(See Power Modes for related discussion.)
SSTRB goes low on the falling edge of the last bit of the
conversion byte, and it returns high when the conversion
is complete. For best noise performance, SCLK should
remain low while SSTRB is low. Typical conversion times
are 2.2ms for temperature measurements and 1.1ms for
voltage measurements. The MSB of the 2 output bytes is
present at DOUT starting at the rising edge of SSTRB.
Successive SCLK falling edges shift the two 8-bit data
bytes out from an internal register. Additional (>16)
SCLK edges will result in zeros on DOUT.
SSTRB does not go into a high-impedance state when CS
goes high. Pulling CS high prevents data from being
clocked in or out, but it does not adversely affect a con-
version in progress. Figure 6 shows SSTRB timing details.
Subsequent conversions with the same reference mode
do not require a configuration byte.
Reference Selection
Select between internal and external voltage modes
through bit REF of the configuration byte. Set REF = 1
for internal reference mode and REF = 0 for external
reference mode.
