TI Class-G Technology Significantly Prolongs
The TPA6140A2 (also known as TPA6140) is a
Battery Life and Music Playback Time
Class-G DirectPath stereo headphone amplifier
with built-in I2C volume control. Class-G technology
–
0.6 mA / Ch Quiescent Current
maximizes battery life by adjusting the voltage
–
50% to 80% Lower Quiescent Current than
supplies of the headphone amplifier based on the
Ground-Referenced Class-AB Headphone
audio signal level. At low level audio signals, the
Amplifiers
internal supply voltage is reduced to minimize power
DirectPathTM Technology Eliminates Large
dissipation.
DirectPathTM
technology
eliminates
external DC-blocking capacitors.
Output DC-Blocking Capacitors
–
Outputs Biased at 0 V
The device operates from a 2.5 V to 5.5 V supply
voltage. Class-G operation keeps total supply current
–
Improves Low Frequency Audio Fidelity
below 5.0 mA while delivering 500
μW per channel
I2C Volume Control
into 32
. Shutdown mode reduces the supply
–
–59 dB to +4 dB Gain
current to less than 3
μA and is activated through the
I2C interface.
Active Click and Pop Suppression
Fully Differential Inputs Reduce System Noise
The TPA6140A2 (TPA6140) I2C register map is
compatible to the TPA6130A2, simplifying software
–
Also Configurable as Single-Ended Inputs
development.
SGND Pin Eliminates Ground Loop Noise
The
amplifier
outputs
have
short-circuit
and
Wide Power Supply Range: 2.5 V to 5.5 V
thermal-overload protection along with ±8 kV HBM
100 dB Power Supply Noise Rejection

Short-Circuit Current Limiter
compliance to the IEC 61000-4-2 ESD standard.
Thermal-Overload Protection
The TPA6140A2 (TPA6140) is available in a 0,4 mm
