PART[1:0]
Part Number. These bits are constant for the AD7763.
13 to 11
DIE[2:0]
Die Number. These bits reflect the current AD7763 die number for identification purposes within a system.
10
0
0 must be written to this bit.
9
LPWR
Low Power. If the AD7763 is operating in low power mode, this bit is set to 1.
8
OVR
If the current analog input exceeds the current overrange threshold, this bit is set.
7
DL_OK
When downloading a user filter to the AD7763, a checksum is generated. This checksum is compared to
the one downloaded following the coefficients. If these checksums agree, this bit is set.
6
FILTER_OK
When a user-defined filter is in use, a checksum is generated when the filter coefficients pass through
the filter. This generated checksum is compared to the one downloaded. If they match, this bit is set.
5
UFILTER
If a user-defined filter is in use, this bit is set.
4
BYP F3
Bypass Filter 3. If Filter 3 is bypassed by setting the relevant bit in Control Register 1, this bit is also set.

1
1 must be written to this bit.
2 to 0
DEC[2:0]
Decimation Rate. These bits correspond to the bits set in Control Register 1.
OFFSET REGISTER—ADDRESS 0X003
Non Bit-Mapped, Default Value 0x0000
The offset register uses twos complement notation and is scaled so
that 0x7FFF (maximum positive value) and 0x8000 (maximum
negative value) correspond to an offset of +0.390625% and
0.390625%, respectively. Offset correction is applied after any gain
correction. Using the default gain value of 1.25 and assuming a
reference voltage of 4.096 V, the offset correction range is
approximately ±25 mV.
GAIN REGISTER—ADDRESS 0X004
Non Bit-Mapped, Default Value 0xA000
The gain register is scaled so that 0x8000 corresponds to a gain
of 1.0. The default value of this register is 1.25 (0xA000). This
gives a full-scale digital output when the input is at 80% of VREF.
This ties in with the maximum analog input range of ±80% of
VREF p-p.
OVERRANGE REGISTER—ADDRESS 0X005
Non Bit-Mapped, Default Value 0xCCCC
The overrange register value is compared with the output of the
first decimation filter to obtain an overload indication with
minimum propagation delay. This is prior to any gain scaling or
offset adjustment. The default value is 0xCCCC, which
corresponds to 80% of VREF (the maximum permitted analog
input voltage). Assuming VREF = 4.096 V, the bit is then set when
the input voltage exceeds approximately 6.55 V p-p differential.
Note that the overrange bit is also set immediately if the analog
input voltage exceeds 100% of VREF for more than 4 consecutive
samples at the modulator rate.
