Description
At 3.3v, the TS4973 is an Audio Power Amplifier capable of delivering 500mW of continuous RMS output power into a 8Ω bridged-tied loads with 1% THD+N, and 150mWof continuous average power into 32Ω. An external standby mode control reduces the supply current to less than 10nA. An internal over-temperature shutdown protection is provided.
■ Operating from VCC = 2.8V to 5.5V
■ RAIL TO RAIL Input/Output
■ 1.2W output power @ Vcc=5V, THD=1%,
F=1kHz, with 8Ω load
■ Ultra low consumption in standby mode
(10nA)
■ 53dB PSRR @ 217Hz from 2.8 to 5V
■ Low distortion (0.5%)
■ Gain settings pin: GS
■ Unity gain stable
■ Available in lead free flip-chip 9 x 300µm
bumps
Applications
■ Mobile phones (cellular / cordless)
■ PDAs
■ Laptop/Notebook computers
■ Portable audio devices
