1 / 46 page  This is information on a product in full production. February 2019 DocID8396 Rev 7 1/46 TS4890 Rail-to-rail output 1 W audio power amplifier with standby mode active low Datasheet - production data Features • Operating from VCC= 2.2 V to 5.5 V • 1 W rail-to-rail output power @ VCC= 5 V, THD=1%, f=1 kHz, with 8 Ω load • Ultra low consumption in standby mode (10 nA) • 75 dB PSSR @ 217 Hz from 5 to 2.2 V • Pop and click reduction circuitry • Ultra low distortion (0.1%) • Unity gain stable • Available in SO8 and MiniSO8 Applications • Mobile phones (cellular/cordless) • Laptop/notebook computers • PDAs • Portable audio devices Description The TS4890 is an audio power amplifier, which can deliver 1 W of continuous RMS output power into 8 W load @ 5 V. This audio amplifier shows 0.1% distortion level (THD) from a 5 V supply for a Pout = 250 mW RMS. An external standby mode control reduces the supply current to less than 10 nA. An internal thermal shutdown protection is also provided. The TS4890 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. Table 1. Device summary(1) 1. Available in tape and reel only.
