Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Production testing for single 3.14V supply is achieved by using
the equivalent dual supplies of ±1.57V.
Note 3: Production testing for single 4.75V supply is achieved by
using the equivalent dual supplies of ±2.375V.
Note 4: Pin 7 (AGND) is the internal analog ground of the device. For
single supply applications this pin should be bypassed with a 1F
capacitor. The biasing voltage of AGND is set with an internal resistive
divider from Pin 8 to Pin 23 (see Block Diagram).
Note 5: Side D is guaranteed by design.
Note 6: See Typical Performance Characteristics.
