CLASS-G DIRECTPATH™ STEREO HEADPHONE AMPLIFIER

WITH I²C VOLUME CONTROL

FEATURES

DESCRIPTION

•

TI Class-G Technology Significantly Prolongs

Battery Life and Music Playback Time

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. DirectPath^TMtechnology eliminates

external DC-blocking capacitors.

–

0.6 mA / Ch Quiescent Current

50% to 80% Lower Quiescent Current than

Ground-Referenced Class-AB Headphone

Amplifiers

•

DirectPath^TMTechnology Eliminates Large

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

below 5.0 mA while delivering 500 µW per channel

into 32 Ω. Shutdown mode reduces the supply

current to less than 3 µA and is activated through the

I²C interface.

The TPA6140A2 (TPA6140) I²C register map is

compatible to the TPA6130A2, simplifying software

development.

Improves Low Frequency Audio Fidelity

I²C Volume Control

–

–59 dB to +4 dB Gain

•

Active Click and Pop Suppression

Fully Differential Inputs Reduce System Noise

–

Also Configurable as Single-Ended Inputs

•

SGND Pin Eliminates Ground Loop Noise

Wide Power Supply Range: 2.5 V to 5.5 V

100 dB Power Supply Noise Rejection

Short-Circuit Current Limiter

The amplifier outputs have short-circuit and

thermal-overload protection along with ±8 kV HBM

ESD

protection,

simplifying

end

equipment

compliance to the IEC 61000-4-2 ESD standard.

Thermal-Overload Protection

The TPA6140A2 (TPA6140) is available in a 0,4 mm

pitch, 16-bump 1,6 mm × 1,6 mm WCSP (YFF)

package.
