STMicroelectronics TS4871
The TS4871 is an audio power amplifier capable of delivering 1 W of continuous RMS output power into 8 Ω load @ 5 V. This audio amplifier exhibits 0.1% distortion level (THD) from a 5 V supply for a Pout = 250 mW RMS. The TS4871 has been designed for high quality audio applications such as mobile phones and to minimize the number of external components.FEATURES
● Operating from VCC = 2.5 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 PSRR @ 217 Hz from 5 V to 2.6 V
● Ultra low pop and click
● Ultra low distortion (0.1%)
● Unity gain stable
● Available in MiniSO8
APPLICATIONS
● Mobile phones (cellular / cordless)● Laptop / notebook computers
● PDAs
● Portable audio devices
DESCRIPTION
An external standby mode control reduces the supply current to less than 10 nA. An internal thermal shutdown protection is also provided. The unity-gain stable amplifier can be configured by external gain setting resistors.
