11 / 109 page  [AK7755] 014006643-E-00 2014/10 - 11 - 6. Absolute Maximum Ratings (AVSS=DVSS=0V; Note 2) Parameter Symbol min max Unit Power Supplies Analog Digital1(I/F) Digital2(Core) DVSS-AVSS (Note 2) AVDD TVDD DVDD ΔGND -0.3 -0.3 -0.3 -0.3 4.3 4.3 1.6 0.3 V V V V Input Current, Any Pin Except Supplies IIN － ±10 mA Analog Input Voltage (Note 3) VINA -0.3 (AVDD+0.3)≤4.3 V Digital Input Voltage (Note 4) VIND -0.3 (TVDD+0.3)≤4.3 V Ambient Temperature Ta -40 85 ℃ Storage Temperature Tstg -65 150 ℃ Note 2. All voltages with respect to ground. AVSS and DVSS must be the same voltage. Note 3. The maximum analog input voltage is smaller value between (AVDD+0.3)V and 4.3V. Note 4. The maximum digital input voltage is smaller value between (DVDD+0.3)V and 4.3V. WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal operation is not guaranteed at these extremes. 7. Recommended Operating Conditions (AVSS=DVSS=0V; Note 2) Parameter Symbol min typ max Unit Power Supplies Analog Digital1(I/F) Digital2(Core) AVDD TVDD DVDD 3.0 1.7 1.14 3.3 3.3 1.2 3.6 3.6 1.3 V V V Note 5. AVDD and TVDD must be powered up first before DVDD when DVDD is supplied externally (LDOE pin = “L”). In this case, the power-up sequence between AVDD and TVDD is not critical. When using the internal regulator (LDOE pin = “H”), the power-up sequence between AVDD and TVDD is not critical. But all power supplies must be ON before starting operation of the AK7755 by PDN pin = “H”. Note 6. Do not turn off the power supply of the AK7755 with the power supply of the surrounding device turned on. Pull-up of SDA and SCL pins must not exceed TVDD. * AKM assumes no responsibility for the usage beyond the conditions in this datasheet. |
