9 / 42 page  [AK4490EN] 015013666-E-01 2015/12 - 9 - 6. Absolute Maximum Ratings (AVSS=DVSS=VSSL=VSSR=VREFLL=VREFLR=0V; Note 2) Parameter Symbol Min. Max. Unit Power Supplies: Analog Analog Digital Input Buffer |AVSS DVSS| (Note 3) AVDD VDDL/R DVDD TVDD GND 0.3 0.3 0.3 0.3 - 4.6 6.0 4.6 4.6 0.3 V V V V V Input Current, Any Pin Except Supplies IIN - 10 mA Digital Input Voltage VIND 0.3 DVDD+0.3 V Ambient Temperature (Power applied) Ta 40 85 C Storage Temperature Tstg 65 150 C Note 2. All voltages with respect to ground. Note 3. AVSS, DVSS, VSSL and VSSR must be connected to the same analog ground plane. Note 4. Connect at least 0.1 μF or more decoupling capacitors between VDDL/VDDR and VSSL/VSSR to suppress affections by a static electricity noise or an over voltage (includes over shooting) that exceeds absolute maximum ratings. 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=VSSL=VSSR=VREFLL=VREFLR=0V; Note 2) Parameter Symbol Min. Typ. Max. Unit Power Supplies (Note 5) Analog Analog Digital Input Buffer AVDD VDDL/R DVDD TVDD 3.0 4.75 3.0 1.6 3.3 5.0 3.3 1.8 3.6 5.25 3.6 DVDD V V V Voltage Reference (Note 6) “H” voltage reference “L” voltage reference VREFHL/R VREFLL/R VDDL/R 0.5 - VSSL/R VDDL/R - V V Note 2. All voltages with respect to ground. Note 5. Each power-up/down sequence is shown below. <Power-Up> 1. PDN pin = “L” 2. TVDD (1.8V) power-up 3. AVDD, DVDD (3V) power-up 4. VREFHL/R and VDDL/R (5V) power-up 5. The PDN pin is allowed to be “H” after all power supplies are applied and settled. otherwise power up the 1.8V power supply, the 3.3V power supplies and the 5V power supplies at the same time. <Power-down> 1. PDN pin = “L” 2. VREFHL/R and VDDL/R (5V) power-down 3. AVDD, DVDD (3V) power-down 4. TVDD (1.8V) power-down Note 6. The analog output voltage scales with the voltage of (VREFH VREFL). AOUT (typ.@0dB) = (AOUT+) (AOUT) = 2.8Vpp (VREFHL/R VREFLL/R)/5. * AKM assumes no responsibility for the usage beyond the conditions in this data sheet. |
