Exposure to absolute maximum rating conditions for DRVDD DGND –0.3 +3.9 V an extended period of time may affect device reliability. AGND DGND –0.3 +0.3 V
EXPLANATION OF TEST LEVELS
AVDD DRVDD –3.9 +3.9 V
Test
Digital DGND –0.3 DRVDD + 0.3 V
Levels Description
Outputs I 100% production tested. CLK, MODE AGND –0.3 AVDD + 0.3 V II 100% production tested at 25°C and sample tested at VIN+, VIN– AGND –0.3 AVDD + 0.3 V specified temperatures.

Storage Temperature –65 +150 °C 1 Typical thermal impedances (28-lead TSSOP), θJA = 67.7°C/W; (32-lead LFCSP), θJA = 32.5°C/W, θJC = 32.71°C/W. These measurements were taken on a 4-layer board in still air, in accordance with EIA/JESD51-1.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy elec- trostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Rev.
