4. Wait for the second low-to-high transistion (middle of
DMY bit).
5. Wait 3/4 of a clock cycle.
6. Sample bit CH1, wait for transistion.
7. Wait 3/4 of a clock cycle.
8. Sample bit CH0, wait for transistion.
9. Wait 3/4 of a clock cycle.
10. Sample ADC9, wait for transistion.
11. Continue until all bits are read.
APPLICATIONS INFORMATION
The above procedure can be ported to a microcontroller
or used to design a state machine in FPGA. Code should
have timeouts in case an edge is missed. Abort the read
if it takes more than double the typical time (1.2ms) for
all 18 bits to be clocked out.
A typical application circuit with the LTC4261/LTC4261-2
in the broadcast mode is illustrated in Figure 17, where
input voltage, VDS of the FET and VSENSE are monitored.
Register Addresses and Contents
The register addresses and contents are summerized in
Table 1 and Table 2. The function of each register bit is
detailed in Tables 3 to 9.
