6.1 Absolute Maximum Ratings

over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
Supply voltage DVDD, AVDD, DR_VDD –0.3 3.6 V
PVDD –0.3 30
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(4)
5-V tolerant MCLK input –0.5 AVDD + 2.5(4)
AMP_OUT_x to GND 32(3) V
BSTRP_x to GND 39(3) V
PVDD Supply voltage for power stage 28(5)(6) V
Operating free-air temperature 0 85 °C
Storage temperature range, Tstg –40 125 °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.
(5) For operation at PVDD levels greater than 18 V, the modulation limit must be set to 96.1 % or lower via the control port register 0x10.
(6) 26.4 V is the maximum recommended operating voltage for continuous operation of the TAS5751M device. Testing and characterization of the device is performed up to and including 28 V to ensure “in system” design margin. 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.
