5 / 10 page 5 DS1165F1 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. Parameter Symbol Min Max Units Supply voltage 1 1.All voltages are measured with respect to GND. VDD –0.3 4.2 V Operating temperature range TA –40 +105 ºC Storage temperature prior to soldering TStgp —30 ºC Storage relative humidity prior to soldering RHStgp —60 % Storage temperature after soldering TStg –40 +105 ºC 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 Test conditions (unless specified otherwise): GND = 0 V; voltages are with respect to ground; performance data taken with VDD = 1.8 V, RL = 10 k, CL = 100 pF, TA = +25ºC, 55 ±15% RH; 1 kHz test signal. Parameter 1 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.
