To convert from digital to analog, the device uses a high performance DAC with Burr Brown™ audio technology. It requires only two power supplies: one DVDD for low-voltage circuitry and one PVDD for high-voltage circuitry. It is controlled by a software control port using standard I2C communication. An optimal mix of thermal performance and device cost is provided in the 90 mΩ rDS(on) of the output MOSFETs. Additionally, a thermally enhanced 48-Pin TSSOP provides excellent operation in the elevated ambient temperatures found in modern consumer electronic devices. Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) TAS5780M TSSOP (48) 12.50 mm × 6.10 mm (1) For all available packages, see the orderable addendum at the end of the data sheet.
