Description
CONFIG3
UNI
Unipolar/Bipolar Operation Selection Bit.
Set by the user to enable unipolar operation. In this mode, the device uses straight binary output coding
i.e., 0 differential input will generate a result of 0000h and a full-scale differential input will generate a
code of FFFFh.
Cleared by the user to enable pseudo-bipolar operation. The device uses offset binary coding, i.e., a nega-
tive full-scale differential input will result in a code of 0000h, a 0 differential input will generate a code of
8000h, while a positive full-scale differential input will result in a code of FFFFh.
CONFIG2
RN2
This bit is used in conjunction with RN1 and RN0 to select the analog input range as shown below.
CONFIG1
RN1
This bit is used in conjunction with RN2 and RN0 to select the analog input range as shown below.
CONFIG0
RN0
This bit is used in conjunction with RN2 and RN1 to select the analog input range as shown below.
Filter Register (A1, A0 = 1, 0; Power-On-Reset = 45h)
The Filter Register is an 8-bit register from which data can be
read or to which data can be written. This register determines
the amount of averaging performed by the sinc filter. Table VIII
outlines the bit designations for the Filter Register. FR7 through
FR0 indicate the bit location, FR denoting the bits are in the
Filter Register. FR7 denotes the first bit of the data stream. The
number in brackets indicates the power-on/reset default status
of that bit. The number in this register is used to set the decima-
tion factor and thus the output update rate for the ADC. The
Filter Register cannot be written to by the user while the ADC
is active. The update rate is calculated as follows:
f
SF
f
ADC
MOD
=
1
3
1
8
where:
fADC is the ADC output update rate.
fMOD is the Modulator Clock Frequency = 32.768 kHz.
SF is the decimal value written to the SF Register.
The allowable range for SF is 13dec to 255dec. Examples of SF
values and corresponding conversion rate (fADC) and time (tADC)
are shown in Table IX. It should also be noted that the ADC
input channel is chopped to minimize offset errors. This means
that the time for a single conversion or the time to the first con-
version result is 2
tADC.
ADC Data Result Register (A1, A0 = 1, 1; Power-On-Reset =
0000h)
The conversion result is stored in the ADC Data Register (DATA).
This register is 16-bits wide. This is a read-only register. On
completion of a read from this register, the RDY bit in the
Status Register is cleared.
