4. Integrator Time Constant: Defines the Integration Time
Constant for the system. The first 3 bits are used for the
address and the last 5 bits for the value. 110TTTTT
Example: 11000011 would be the integrator time
constant (110 on for the first 3 bits) and an integration
constant of 55
μ
s (bit value of 3 in Table 2).

, the first 3 bits are used for the address,
and the last 5 bits are used for the value. The options are:
- If CS is “0” channel “0” is selected. If CS is “1” channel “1”
is selected.
- If C
A
is “0” attenuation applies to the knock filter. If C
A
is
“1” attenuation applies to the reference filter.
- During the test mode (TEST input is a low level), if T
A
is “0”
all sections get their input from the output of the
antialiasing filter input. This input can come from either the
output of channel “0” amplifier or channel “1” output
depending upon the state of the C
S
bit. If T
A
is “0” the input
amplifiers are powered down. If T
A
is set to “1” during the
test mode the chip is configured in its normal operating
state, getting inputs to all sections from previous sections.
- Combinations of T

different analog parts of the circuit. Table 1 shows these
combinations.Allblocksexceptfortheantialiasingfilterare
