TPA2051D3

The TPA2051D3 is an audio subsystem with a mono Class-D power amplifier, a stereo DirectPath headphone amplifier, and bypass switches. The DirectPath headphone amplifier eliminates the need for external dc-blocking output capacitors. The built-in charge pump creates a negative supply voltage for the headphone amplifier, allowing a 0 V dc bias at the output. The DirectPath headphone amplifier drives 25 mW into 16 Ω speakers from a 4.2 V supply.

Features of the TPA2051D3 are:(1)Mono Class-D Amp: 730 mW into 8 from 3.6 V Supply (1% THD); (2)Class-D Bypass Switches; (3)DirectPath ? Stereo Headphone Amplifier No Output Capacitors Required; (4)SpeakerGuard  Automatic Gain Control (AGC); (5)One Differential Mono and Two Stereo Single-Ended Inputs; (6)3:1 Input MUX with Mode Control; (7)32-Step Volume Control for Both Input Channels; (8)Independent Volume Controls for All Inputs; (9)Independent Shutdown for Headphone and Class-D Amplifiers; (10)I2C ? Interface; (11)Short-Circuit and Thermal-Overload Protection; (12)Operates from 2.5 V to 5.5 V; (13)25-Ball 2,16 mm * 2,11 mm, 0,4 mm pitch WCSP.

The absolute maximum ratings of the TPA2051D3 can be summarized as:(1)Supply voltage, AVDD, PVDD : 0.3 V to 6.0 V; (2)I2C Supply Voltage DVDD: 0.3 to 3.6 V; (3)Input Voltage: 0.3 V to AVDD + 0.3 V; (4)Operating free-air temperature range : 40 ° C to 85 ° C; (5)Operating junction temperature range : 40 ° C to 150 ° C; (6)Storage temperature range : 65 ° C to 85 ° C.
