TPA2005D1ZQTR

The TPA2005D1ZQTR is designed as one kind of 1.4-W high-efficiency filter-free class-D audio power amplifier. It can be used in IPdDeAalsfor wireless or cellular handsets and PDAs. This device is a fully differential amplifier with differential inputs and outputs which consists of a differential amplifier and a common-mode amplifier.

Features of the TPA2005D1ZQTR are:(1)qualification in accordance with AEC-Q100;(2)qualified for automotive applications;(3)customer-specific configuration control can be supported along with major-change approval;(4)1.4 W into 8 W from a 5-V supply at THD=10% (typ);(5)maximum battery life and minimum heat:2.8-mA quiescent current and 0.5-mA shutdown current;(6)optimized PWM output stage eliminates LC output filter;(7)improved CMRR eliminates two input coupling capacitors;(8)3 mm x 3 mm QFN package (DRB).

The absolute maximum ratings of the TPA2005D1ZQTR can be summarized as:(1)supply voltage (in active mode):-0.3 V to 6 V;(2)supply voltage (In shutdown mode):-0.3 V to 7 V;(3)input voltage:-0.3 V to VDD+0.3 V;(4)continuous total power dissipation:see dissipation rating table;(5)operating free-air temperat-ure:-40°C to 85°C;(6)operating junction temperature:-40°C to 150°C;(7)storage temperature:-65°C to 85°C;(8)lead temperature 1,6 mm (1/16 inch) from case for 10 seconds:260°C.
