6 Specifications

6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
VALUE UNIT
Supply voltage DVDD, AVDD –0.3 to 3.6 V
PVDD –0.3 to 20
Input voltage 3.3-V digital input –0.5 to DVDD + 0.5 V
5-V tolerant(2) digital input (except MCLK) –0.5 to DVDD + 2.5(4)
5-V tolerant MCLK input –0.5 to AVDD + 2.5(4)
AMP_OUT_x to GND 22(3) V
BSTRP_x to GND 29(3) 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, LRCK, MCLK, SDIN, SDA, and SCL.
(3) DC voltage + peak ac waveform measured at the pin should be below the allowed limit for all conditions.
(4) Maximum pin voltage should not exceed 6 V.

6.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±4000 V
Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±1500
(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

MIN NOM MAX UNIT
DVDD, AVDD Digital, analog supply voltage 3 3.3 3.6 V
PVDD Output power devices supply voltage 8 16.5(1)(2) 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
RL Load impedance 4 8 Ω
RL Load impedance in PBTL 2 Ω
LO Output-filter inductance Minimum output inductance under short-circuit condition 10 μH
(1) For operation at PVDD levels greater than 14.5 V, the modulation limit must be set to 96.1% or lower via the control port register 0x10.
(2) 16.5 V is the maximum recommended voltage for continuous operation of the TAS5733L device. Testing and characterization of the device is performed up to and including 16.5 V to ensure “in system” design margin. However, continuous operation at these levels is not recommended. Operation above the maximum recommended voltage may result in reduced performance, errant operation, and reduction in device reliability.

(3) The junction-to-case (top) thermal resistance is obtained by simulating a cold plate test on the package top. No specific JEDEC-standard test exists, but a close description can be found in the ANSI SEMI standard G30-88.
(4) The junction-to-board thermal resistance is obtained by simulating in an environment with a ring cold plate fixture to control the PCB temperature, as described in JESD51-8.
(5) The junction-to-top characterization parameter, ψJT, estimates the junction temperature of a device in a real system and is extracted from the simulation data for obtaining RθJA, using a procedure described in JESD51-2a (sections 6 and 7).

NOTE:

On power up, hold the TAS5733L RST LOW for at least 100 μs after DVDD has reached 3 V.

NOTE:

If RST is asserted LOW while PDN is LOW, then RST must continue to be held LOW for at least 100 μs after PDN is deasserted (HIGH).
