Texas Instruments TPA6138A2PW Audio Power Amplifier 40 mW 2 Channel 3V to 3.6V Tssop 14 Pins

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.
