These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum conditions for extended periods may affect device reliability. (2) 5-V tolerant inputs are PDN, RST, SCLK, LRCLK, MCLK, SDIN, SDA, and SCL. (3) Maximum pin voltage should not exceed 6 V. (4) DC voltage + peak AC waveform measured at the pin should be below the allowed limit for all conditions. 7 Specifications 7.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted). (1) MIN MAX UNIT Supply voltage DVDD, AVDD, DRVDD –0.3 3.6 V PVDD –0.3 30 V DR_INx –0.3 DRVDD + 6 V Input voltage 3.3-V digital input –0.5 DVDD + 0.5 V 5-V tolerant(2) digital input (except MCLK) –0.5 DVDD + 2.5(3) 5-V tolerant MCLK input –0.5 AVDD + 2.5(3) SPK_OUTx to GND 32(4) V BSTRPx to GND 39(4) V Operating free-air temperature 0 85 °C Storage temperature, Tstg –40 125 °C (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. 7.2 ESD Ratings VALUE UNIT V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±1000 V Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±250 (1) For operation at PVDD levels greater than 18 V, the modulation limit must be set to 93.8% via the control port register 0x10. (2) Continuous operation above the recommended junction temperature may result in reduced reliability and/or lifetime of the device. 7.3 Recommended Operating Conditions MIN NOM MAX UNIT xVDD Digital, analog, headphone supply voltage 3 3.3 3.6 V PVDD Half-bridge supply voltage 8 26.4(1) V VIH High-level input voltage 5-V tolerant 2 V VIL Low-level input voltage 5-V tolerant 0.8 V TA Operating ambient temperature 0 85 °C TJ (2) Operating junction temperature 0 125 °C RSPK (SE, BTL, and PBTL) Minimum supported speaker impedance Output filter: L = 15 μH, C = 330 nF 4 8 Ω Lo(BTL) Output-filter inductance Minimum output inductance under short-circuit condition 10 μH RHP Headphone mode load impedance 16 32 Ω RLD Line-diver mode load impedance 0.6 10 k Ω |
