6 / 116 page TAS5548 SLES270A – NOVEMBER 2012 – REVISED APRIL 2015 www.ti.com 6 Specifications 6.1 Absolute Maximum Ratings (1) MIN MAX UNIT Supply voltage, DVDD1 and DVDD2 –0.3 3.9 V Supply voltage, AVDD and AVDD_PWM –0.3 3.9 V 3.3-V digital input –0.5 DVDD + 0.5 Input voltage V 5-V tolerant(2) digital input –0.5 6 IIK Input clamp current (VI < 0 or VI > 1.8 V ±20 μA IOK Output clamp current (VO < 0 or VO > 1.8 V) ±20 μA TSTG Storage temperature range –65 150 °C (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only. Functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions are not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) 5-V tolerant signals are RESET, PDN, MUTE, HP_SEL, SCLK, LRCLK, MCLK, SDIN1, SDIN2, SDIN3, SDIN4, SDA, and SCL. 6.2 ESD Ratings VALUE UNIT Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, ±250 V all pins (1) V(ESD) Electrostatic discharge Charged device model (CDM), per JEDEC specification ±1000 V JESD22-C101, all pins (2) (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. 6.3 Recommended Operating Conditions over 0°C to 85°C MIN NOM MAX UNIT Digital supply voltage, DVDD1 and DVDD2 3 3.3 3.6 V Analog supply voltage, AVDD and AVDD_PWM 3 3.3 3.6 V 3.3 V 2 VIH High-level input voltage 5-V tolerant 2 V 1.8-V LVCMOS (XTL_IN) 1.26 3.3 V 0.8 VIL Low-level input voltage 5-V tolerant 0.8 V 1.8-V (XTL_IN) 0.54 TA Operating ambient-air temperature 0 25 85 °C TJ Operating junction temperature 0 105 °C 6.4 Thermal Information TAS5548 THERMAL METRIC(1) DCA (HTSSOP) UNIT 56 PINS RθJA Junction-to-ambient thermal resistance 26.1 RθJCtop Junction-to-case (top) thermal resistance 13.0 RθJB Junction-to-board thermal resistance 8.0 °C/W ψJT Junction-to-top characterization parameter 0.4 ψJB Junction-to-board characterization parameter 7.9 RθJCbot Junction-to-case (bottom) thermal resistance 0.4 (1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953. 6 Submit Documentation Feedback Copyright © 2012–2015, Texas Instruments Incorporated Product Folder Links: TAS5548 |
