The TS46x are a family of operational amplifiers able to operate with voltages as low as ±1.35V and to reach a minimum of ±2Vpp of output swing when supplied with ±2.5V. This device is well-suited for all kinds of portable and battery-supplied equipment, where low noise and low distortion are key requirements. The TS461/2/4 offer excellent output rail-to-rail performance at an attractive cost.

The TS472 is a differential-input microphone preamplifier optimized for high-performance PDA and notebook audio systems. This device features an adjustable gain from 0 to 40 dB with excellent power-supply and commonmode rejection ratios. In addition, the TS472 has a very low noise microphone bias generator of 2 V. It also includes a complete shutdown function, with active low standby mode.

The TS4871 is an Audio Power Amplifier capable of delivering 1W of continuous RMS Ouput Power into 8load @ 5V. This Audio Amplifier is exhibiting 0.1% distortion level (THD) from a 5V supply for a Pout = 250mW RMS. An external standby mode control reduces the supply current to less than 10nA. An internal thermal shutdown protection is also provided. The TS4871 has been designed for high quality audio applications such as mobile phones and to minimize the number of external components. The unity-gain stable amplifier can be configured by external gain setting resistors.

The TS488 is a dual audio power amplifier capable of driving, in single-ended mode, either a 16 Ω or a 32 Ω stereo headset. The TS488 eliminates pop and click noise and reduces the number of required external passive components. Capable of descending to low voltages, it delivers up to 31 mW per channel (into 16 Ω loads) of continuous average power with 0.1% THD+N in the audio bandwidth from a 2.5 V power supply. An externally-controlled standby mode reduces the supply current to 10 nA (typ.). The unity gain stable is configured by external gain-setting resistors.
