Differential stereo inputs and built-in – Excellent Low Frequency Fidelity resistors set the device gain, further reducing external component count. Gain is selectable at –6 dB, 0 dB, • Active Click and Pop Suppression 3 dB or 6 dB. The amplifier drives 25 mW into 16 Ω • 2.1 mA Typical Supply Current speakers from a single 2.3 V supply. The TPA6132A2 • Fully Differential or Single-Ended Inputs (TPA6132) provides a constant maximum output power independent of the supply voltage, thus – Built-In Resistors Reduces Component Count facilitating the design for prevention of acoustic – Improves System Noise Performance shock. • Constant Maximum Output Power from 2.3 V to The TPA6132A2 features fully differential inputs to 5.5 V Supply reduce system noise pickup between the audio – Simplifies Design to Prevent Acoustic Shock source and the headphone amplifier. The high power • Improved RF Noise Immunity supply noise rejection performance and differential architecture provides increased RF noise immunity. • MicrosoftTM Windows VistaTM Compliant For single-ended input signals, connect INL+ and • High Power Supply Noise Rejection INR+ to ground. – 100 dB PSRR at 217 Hz The device has built-in pop suppression circuitry to – 90 dB PSRR at 10 kHz completely eliminate disturbing pop noise during turn- • Wide Power Supply Range: 2.3 V to 5.5 V on and turn-off. The amplifier outputs have short- circuit and thermal-overload protection along with • Gain Settings: –6 dB, 0 dB, 3 dB, and 6 dB ±8 kV HBM ESD protection, simplifying end • Short-Circuit and Thermal-Overload Protection equipment compliance to the IEC 61000-4-2 ESD • ±8 kV HBM ESD Protected Outputs standard. • Small Package Available The TPA6132A2 operates from a single 2.3 V to – 16-Pin, 3 mm × 3 mm Thin QFN 5.5 V supply with 2.1 mA of typical supply current. Shutdown mode reduces supply current to less than 2 Applications 1 μA. • Smart Phones / Cellular Phones Device Information(1) • Notebook Computers PART NUMBER PACKAGE BODY SIZE (NOM) • CD / MP3 Players TPA6132A2 WQFN (16) 3.00 mm x 3.00 mm • Portable Gaming (1) For all available packages, see the orderable addendum at the end of the datasheet. 4 Simplified Schematic 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
