TPA6135A2

The TPA6135A2 (sometimes referred to as TPA6135 is a DirectPath  stereo headphone amplifier tha eliminates the need for external dc-blocking outpu capacitors. Differential stereo inputs and built-in resistors set the device gain, further reducing externa component count. Gain is selectable at 0 dB or 6 dB The amplifier drives 25 mW into 16  speakers from a single 2.3 V supply. The TPA6135A2 (TPA6135 provides a constant maximum output powe independent of the supply voltage, thus facilitating the design for prevention of acoustic shock.

Features of the TPA6135A2 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; (4)2.1 mA Typical Supply Current; (5)Fully Differential or Single-Ended Inputs Built-In Resistors Reduces Component Count Improves System Noise Performance ; (6)Constant Maximum Output Power from 2.3 V to 5.5 V Supply Simplifies Design to Prevent Acoustic Shock; (7)Improved RF Noise Immunity; (8)Microsoft TM Windows Vista TM Compliant; (9)High Power Supply Noise Rejection 100 dB PSRR at 217 Hz 90 dB PSRR at 10 kHz; (10)Wide Power Supply Range: 2.3 V to 5.5 V; (11)Gain Settings: 0 dB and 6 dB; (12)Short-Circuit and Thermal-Overload Protection; (13)± 8 kV HBM ESD Protected Outputs.

The absolute maximum ratings of the TPA6135A2 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)g Storage temperature range : 65 ° C to 150 ° C.
