The device is ideal for single-supply electronics where size and cost are critical design • High SNR, >90 dB parameters. • Differential Input and Single-Ended Output Designed using TI’s patented DirectPath™ • Adjustable Gain by External Gain-Setting technology, The TPA6138A2 is capable of driving 25 Resistors mW into a 32- Ω load with 3.3-V supply voltage. The • Configurable as a Second-Order Low-Pass Filter device has differential inputs and uses external gain- – Ideal for PWM Audio Sources setting resistors that supports a gain range of ±1 V/V to ±10 V/V. Gain can be configured individually for • Low DC Offset, <1 mV each channel. The device can also be configured as • Ground-Referenced Outputs Eliminate DC- a second-order low-pass filter and is ideal for Blocking Capacitors interfacing with PWM audio sources. Audio output – Reduce Board Area compiles with ±8-kV IEC ESD protection, requiring just a simple resistor-capacitor ESD protection circuit. – Reduce Component Cost The TPA6138A2 has built-in active-mute control for – Improve THD+N Performance pop-free audio on/off control. The TPA6138A2 has an – No Degradation of Low-Frequency Response external undervoltage detector that mutes the output Due to Output Capacitors when the power supply is removed, ensuring a pop- free shutdown. • Short-Circuit Protection • Click- and Pop-Reduction Circuitry Using the TPA6138A2 in audio products can reduce component count considerably compared to • External Undervoltage Mute traditional headphone amplifiers. The TPA6138A2 • Active Mute Control for Pop-Free Audio On/Off does not require a split-rail power supply or a dc Control blocking capacitor. The TPA6138A2 integrates its • Space-Saving TSSOP Package own charge pump to generate a negative supply rail that provides a clean, pop-free ground-biased audio signal. 2 Applications The TPA6138A2 is available in a 14-pin TSSOP. • LCD and PDP TV • Blu-ray Disc™, DVD Players Device Information(1) • Set-Top Boxes PART NUMBER PACKAGE BODY SIZE (NOM) • Mini/Micro Combo Systems TPA6138A2 TSSOP (14) 5.00 mm × 4.40 mm • Sound Cards (1) For all available packages, see the orderable addendum at • Laptops the end of the datasheet.
