CS7331P

3 Characteristics and Specifications

Table 3-3. Absolute Maximum Ratings

Absolute maximum ratings are stress ratings only. Permanent damage to the device may be caused by continuously operating at or beyond these limits.

Device functional operating limits and guaranteed performance specifications are given under electrical characteristics at the test conditions specified.

ESD-sensitive device. The CS7331P is manufactured on a CMOS process. It is therefore generically susceptible to damage from

excessive static voltages. Proper ESD precautions must be taken during handling and storage of this device. This device is

qualified to current JEDEC ESD standards

Table 3-4. Acoustic and Electrical Characteristics

1.All performance measurements are specified with a 20-kHz, low-pass brick-wall filter and, where noted, an A-weighted filter. The low-pass filter

removes out-of-band noise.
