The TAS5760LD operates with a nominal supply voltage from 4.5 to 15 VDC. – 32, 44.1, 48, 88.2, 96 kHz Sample Rates The device has an integrated DirectPath™ – Headphone Amplifier / Line Driver headphone amplifier and line driver to increase • General Operational Features: system level integration and reduce total solution costs. – Selectable Hardware or Software Control – Integrated Digital Output Clipper An optimal mix of thermal performance and device cost is provided in the 120-m Ω RDS(ON) of the output – Programmable I²C Address (1101100[R/W] or MOSFETs. Additionally, a thermally enhanced 48-Pin 1101101[R/W]) TSSOP provides excellent operation in the elevated – Closed-Loop Amplifier Architecture ambient temperatures found in modern consumer – Adjustable Switching Frequency for Speaker electronic devices. Amplifier The entire TAS5760xx family is pin-to-pin compatible • Robustness Features: in the 48-Pin TSSOP package. Alternatively, to achieve the smallest possible solutions size for – Clock Error, DC, and Short-Circuit Protection applications where pin-to-pin compatibility and a – Overtemperature and Programmable headphone or line driver are not required, a 32-Pin Overcurrent Protection TSSOP package is offered for the TAS5760M and • Audio Performance (PVDD = 12 V, RSPK = 8 Ω, TAS5760L devices. The I2C register map in all of the SPK_GAIN[1:0] Pins = 01) TAS5760xx devices are identical, to ensure low development overhead when choosing between – Idle Channel Noise = 65 µVrms (A-Wtd) devices based upon system-level requirements. – THD+N = 0.09% (at 1 W, 1 kHz) – SNR = 100 dB A-Wtd (Ref. to THD+N = 1%) Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) 2 Applications TAS5760LD HTSSOP (48) 12.50 mm × 6.10 mm • LCD/LED TV and Multipurpose Monitors (1) For all available packages, see the orderable addendum at the end of the datasheet. • Sound Bars, Docking Stations, PC Audio • General-Purpose Audio Equipment Functional Block Diagram Output Power vs PVDD NOTE: Thermal Limits were determined via the TAS5760xxEVM 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
