8 / 71 page  TAS5721 SLOS739 – JULY 2012 www.ti.com ABSOLUTE MAXIMUM RATINGS Over operating free-air temperature range (unless otherwise noted). (1) VALUE UNIT DVDD, AVDD, DRVDD –0.3 to 3.6 V Supply voltage PVDD –0.3 to 30 V DR_INx –0.3 to DRVDD + 6 V V 3.3-V digital input –0.5 to DVDD + 0.5 Input voltage 5-V tolerant(2) digital input (except MCLK) –0.5 to DVDD + 2.5(3) V 5-V tolerant MCLK input –0.5 to AVDD + 2.5(3) SPK_OUTx to GND 32(4) V BSTRPx to GND 39(4) V Operating free-air temperature 0 to 85 °C Storage temperature range, Tstg –40 to 125 °C (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. 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. RECOMMENDED OPERATING CONDITIONS MIN NOM MAX UNIT xVDD Digital, analog, headphone supply 3 3.3 3.6 V voltage 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 range 0 85 °C TJ (2) Operating junction temperature range 0 125 °C RSPK Minimum Supported Speaker (SE, BTL, and Output filter: L = 15 μH, C = 330 nF 4 8 Ω Impedance PBTL) Minimum output inductance Lo(BTL) Output-filter inductance 10 μH under short-circuit condition RHP Headphone mode load impedance 16 32 Ω RLD Line-diver mode load impedance 0.6 10 k Ω (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. ELECTRICAL CHARACTERISTICS I/O Pin Characteristics PVDD = 18 V, AVDD = DRVDD = DVDD = 3.3 V, external components per Typical Application Circuit diagrams, and in accordance with recommended operating conditions (unless otherwise specified). PARAMETER TEST CONDITIONS MIN TYP MAX UNIT IOH = –4 mA VOH High-level output voltage 2.4 DVDD = AVDD = 3 V ADR/FAULT and SDA V IOL = 4 mA VOL Low-level output voltage 0.5 DVDD = AVDD = 3 V VI < VIL ; DVDD = AVDD IIL Low-level input current 75 = 3.6 V Digital Inputs μA VI > VIH ; DVDD = IIH High-level input current 75 AVDD = 3.6 V 8 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated Product Folder Links: TAS5721 |
