TPA6136A2

The TPA6136A2 (sometimes referred to as TPA6136) is a DirectPath ™ stereo headphone amplifier that eliminates the need for external dc-blocking output capacitors. Differential stereo inputs and built-in resistors set the device gain, further reducing external component count. Gain is selectable at 0 dB or 6 dB.The amplifier drives 25 mW into 16 Ω speakers from a single 2.3 V supply. The TPA6136A2 (TPA6136) provides a constant maximum output power independent of the supply voltage, thus facilitating the design for prevention of acoustic shock.

Features of the TPA6136A2 are:(1)Patented DirectPath ? Technology Eliminates Need for DC-Blocking Capacitors Outputs Biased at 0 V Excellent Low Frequency Fidelity; (2)Active Click and Pop Suppression; (3)HI-Z Output Mode Allows Sharing Output Jack; (4)2.1 mA Typical Supply Current; (5)Fully Differential Inputs Reduce System Noise Also Configurable as Single-Ended Inputs; (6)SGND Pin Eliminates Ground Loop Noise; (7)Constant Maximum Output Power from 2.3 V; (8)to 5.5 V Supply; (9) Simplifies Design to Prevent Acoustic; (10)Shock; (11)MicrosoftTM Windows Vista TM Compliant; (12)100 dB Power Supply Noise Rejection; (13)Wide Power Supply Range: 2.3 V to 5.5 V; (14)Gain Settings: 0 dB and 6 dB; (15)Short-Circuit and Thermal-Overload Protection; (16)± 8 kV HBM ESD Protected Outputs; (17)Small Package Available 16-Ball, 1.6 x 1.6 mm, 0.4 mm Pitch WCSP.

The absolute maximum ratings of the TPA6136A2 can be summarized as:(1)Operating free-air temperature range : 40 ° C to 85 ° C; (2)Operating junction temperature range : 40 ° C to 150 ° C; (3)Storage temperature range : 65 ° C to 150 ° C.
