The TS4995 is an audio power amplifier capable of delivering 1.2W of continuous RMS output power into an 8 Ω load at 5 V. It features differential inputs, 90 dB PSRR, 6 dB integrated fixed gain, ultra-low power consumption, selectable standby mode, ultra-fast startup time and ultra-low pop and click noise. It is suitable for applications such as mobile phones, PDAs, and laptop computers.
The TS4995 is a fully differential audio power amplifier designed for high-quality applications such as mobile phones, PDAs, and portable audio devices. It delivers up to 1.2 W of continuous RMS output power into an 8 Ω load at 5 V supply voltage with a fixed internal gain of 6 dB.
Key features include outstanding noise immunity due to differential inputs, ultra-low standby current (less than 10 nA), and thermal shutdown protection. The device operates from a supply voltage range of 2.5 V to 5.5 V and is available in a 9-bump flip chip package.
