Audio Amplifiers

Headphone AmplifiersGeneral Description

The Tempo Semiconductor family of ultra-low power, high-fidelity Speaker and Headphone amplifiers are targeted at a wide variety of markets including: consumer mobile & home, gaming accessories, professional audio, and even IoT / industrial IoT.

With their ultra-low power consumption and high-efficiency, this class of devices are well-suited for portable and battery-powered applications, such as the Target Applications listed below.

In addition to our high-efficiency, high-reliability, wide-range format support digital audio inputs & outputs (I2S / LJ / RJ / TDM) or differential audio inputs, we offer three amplifiers which suite a majority of the battery-powered portable audio applications on the market.

For digital audio input speaker applications with an impedance ranging from 8 Ohms down to 2 Ohms, our ACS32201 with DDX™ Class-D amplifier technology and configurable audio DSP processing fits the bill.

Similarly, for analog audio input source speaker applications that do not require a configurable DSP, the highly energy-efficient and cost-effective TSDP90xx is now also being offered.

Tempo now also offers our new, high-efficiency, differential input, DirectConnect™ TSDP1xx family of stereo 2Vrms (10KΩ) line drivers / 170mW (16Ω) headphone amplifier with and without I2C control.
