Description

The TPA311DGN is designed as a bridge-tied load (BTL) or single-ended (SE) audio power amplifier developed especially for low-voltage applications where internal speakers and external earphone operation are required.

TPA311DGN has eight features. (1)Fully specified for 3.3V and 5V operation. (2)Wide power supply compatibility 2.5V to 5.5V. (3)Output power for Rl=8 which would be 350mW at Vdd=5V, BTL and 250mW at Vdd=5V, SE and 250mW at Vdd=3.3V, BTL and 75mW at Vdd=3.3V, SE. (4)Shutdown control Idd=7A at 3.3V and Idd=60A at 5V. (5)BTL to SE mode control. (6)Integrated depop circuitry. (7)Thermal and short-circuit protection. (8)Surface mount packaging SOIC and powerPAD MSOP. That are all the main features.

Some absolute maximum ratings of TPA311DGN have been concluded into several points as follow. (1)Its supply voltage would be 6V. (2)Its input voltage would be from -0.3V to VDD+0.3V. (3)Its continuous total power dissipation would be internally limited. (4)Its operating free-air temperature range would be from -40°C to 85°C. (5)Its operating junction temperature range would be from -40°C to 150°C. (6)Its storage temperature range would be from 65°C to 150°C. (7)Its lead temperature 1,6 mm (1/16 inch) from case for 10 seconds would be from 260°C. TPA311DGN should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some characteristics of TPA311DGN are concluded as follow. (1)Its output offset voltage (measured differentially) would be typ 5mV and max 20mV. (2)Its power supply rejection ratio would be typ 85dB for BTL mode and would be typ 83dB for SE mode. (3)Its supply current would be typ 0.7mA and max 1.5mA for BTL mode and would be typ 0.35mA and max 0.75mA for SE mode. (4)Its supply current, shutdown mode would be typ 7uA and max 50uA. (5)Its high level input current would be max 1uA. (6)Its low level input current would be max 1uA. And so on.
