Tempo Semiconductor TSDP11xx / TSDP10xx Headphone Amplifiers

Tempo Semiconductor TSDP11xx / TSDP10xx Headphone Amplifiers are class-H capless DirectConnect™ technology amplifiers featuring 2V_rms ultra-low-power. These amplifiers provide independent left/right channel volume control, mute, and fine parameter adjustment via the two-wire I²C compatible serial interface. The TSDP11xx / TSDP10xx headphone amplifiers eliminate large output DC blocking capacitors, reduce board area, and reduce component height and cost. These amplifiers enable full bass response without attenuation, offer no pop on start-up or power-down, and charge-pump allows for true ground-centered outputs.

The Tempo Semiconductor TSDP11xx / TSDP10xx amplifiers offer <1μA shutdown supply current, <1μA shutdown input leakage current, and 230mA headphone output current. These amplifiers operate at 2.5V to 5.5V power supply voltage range and -40°C to 85°C industrial temperature range. Typical applications include gaming-class motherboards, tablet computers, gaming-class laptops, portable gaming platforms, digital audio streaming/connected audio accessories, and remote controls/gaming controllers with headphone jacks.
