First release.

1.10

June 29, 2011

Added specification for “Excitation Frequency of External Capacitances C0 and C1” in section 1.3 and

2.2.1.

Added “PDM frequency” specification to table in section 1.3. In section 3.7, clarified that clipping limit

default values must be adjusted for PDM output functionality. Revised PDM frequency in sections 1.3

and 3.7. Revised PDM ripple and settling time specifications in section 1.3. Revised related examples

in Table 3.12 and corrected equation (14) for calculating ripple. Revisions to text explaining equation

(16) and subsequent text recommending limits for PDM_Clip_High. Revised Table 5.1 for

PDM_Clip_High and PDM_Clip_Low. Added new settings for PDM clipping limits to section 7.2 and

revised related settings in Table 7.2.

Revised section 1.6 for addition of specifications for “Voltage Dependency” for the temperature channel

to section 1.3.

Revisions to section 3.3.2.1 to explain preferred method for detecting valid data.

Revised product ordering codes.

1.30

July 23, 2012

Added note for clarity to “Active Regulated Voltage” specification in section 1.3.

Deleted redundant specification for fOSC in section 1.3.

Revised the “Excitation Frequency of External Capacitances C0 and C1” (fEXC) specification in Table

1.3 to list a separate specification fMULTx for each Mult setting.

Deleted inapplicable row for 2.0V for the “Error Mult 1, -40 to 125°C” specification in section 1.3.

Revised specifications for CVCORE_SM and CVCORE_UM in specifications in section 1.2.
