TPA6140A2

The TPA6140A2 (also known as TPA6140) is a Class-G DirectPath™ stereo headphone amplifier with built-in I2C volume control. Class-G technology maximizes battery life by adjusting the voltage supplies of the headphone amplifier based on the audio signal level. At low level audio signals, the internal supply voltage is reduced to minimize power dissipation. DirectPathTM technology eliminates external DC-blocking capacitors.

Features of the TPA6140A2 are:(1)TI Class-G Technology Significantly Prolongs Battery Life and Music Playback Time 0.6 mA / Ch Quiescent Current 50% to 80% Lower Quiescent Current than Ground-Referenced Class-AB Headphone Amplifiers; (2)DirectPathTM Technology Eliminates Large Output DC-Blocking Capacitors Outputs Biased at 0 V Improves Low Frequency Audio Fidelity; (3)I2C Volume Control 59 dB to +4 dB Gain; (4)Active Click and Pop Suppression; (5)Fully Differential Inputs Reduce System Noise Also Configurable as Single-Ended Inputs; (6)SGND Pin Eliminates Ground Loop Noise; (7)Wide Power Supply Range: 2.5 V to 5.5 V; (8)100 dB Power Supply Noise Rejection; (9)Short-Circuit Current Limiter; (10)Thermal-Overload Protection; (11)Software Compatible with TPA6130A2; (12)0,4 mm Pitch, 1,6 mm * 1,6 mm WCSP Package.

The absolute maximum ratings of the TPA6140A2 can be summarized as:(1)Operating free-air temperature range:40°C to 85°C; (2)Operating junction temperature range: 40°C to 150°C; (3)Storage temperature range :65°C to 85°C.
