1 / 28 page  March 2005 Revision 5 1/28 ■ Operating from V CC = 3V to 5.5V ■ Rail to rail input/output ■ Speaker driver with 1 W output @ Vcc = 5V, THD+N = 1%, F = 1kHz, 8 Ω load ■ Headset drivers with 160 mW output @ Vcc = 5V, THD+N = 1%, F = 1kHz, 32 Ω load ■ Headset output is 30mW in stereo @ Vcc = 3V ■ THD+N < 0.5% Max @ 20mW into 32Ω BTL, 50Hz < Frequency < 20kHz ■ 32-step digital volume control from - 34.5dB to +12dB ■ +6dB power up volume and full standby ■ 8 different output modes ■ Pop & click reduction circuitry ■ Low shutdown current (< 100nA) ■ Thermal shutdown protection ■ Flip-chip package 18 x 300µm bumps Description The TS4851 is a low power audio amplifier that can drive either both a mono speaker or a stereo headset. To the speaker, it can deliver 400 mW (typ.) of continuous RMS output power into an 8 Ω load with a 1% THD+N value. To the headset driver, the amplifier can deliver 30 mW (typ.) per channel of continuous average power into a stereo 32 Ω bridged-tied load with 0.5% THD+N @ 3.3V. This device features a 32-step digital volume control and 8 different output selections. The digital volume and output modes are controlled through a three-digit SPI interface bus.
