Product Overview

The TPA6138A2PW is a pop-free stereo Headphone Amplifier designed to allow the removal of the output DC-blocking capacitors for reduced component count. The device is ideal for single-supply electronics where size and cost are critical design parameters. Designed using TI's patented DirectPath™ technology, the TPA6138A2 is capable of driving 25mW into a 32R load with 3.3V supply voltage. The device has differential inputs and uses external gain-setting resistor that supports a gain range of ±1 to ±10V/V. Gain can be configured individually for each channel. The device can also be configured as a second-order low-pass filter and is ideal for interfacing with PWM audio sources. Audio output compiles with ±8kV IEC ESD protection, requiring just a simple resistor-capacitor ESD protection circuit. The TPA6138A2 has built-in active-mute control for pop-free audio on/off control.
  • Differential input and single-ended output
  • Adjustable gain by external gain-setting resistors
  • Configurable as a second-order low-pass filter
  • Ground-referenced outputs eliminate DC- blocking capacitors
  • Short-circuit protection
  • Click- and pop-reduction circuitry
  • External undervoltage mute
  • Active mute control for pop-free audio on/off control
  • Low THD+N <0.01% at 10mW into 32R
  • >90dB High SNR
  • <1mV Low DC offset
  • Green product and no Sb/Br
