TS4985 2 X 1.2W Stereo Audio Power Amplifier with Dedicated Standby Pins ■ ■ ■ ■ ■ ■ ■ Operating from VCC=2.2V to 5.5V 1.2W output power per channel @ VCC=5V, THD+N=1%, RL=8 10nA standby current 62dB PSRR @ 217Hz with grounded inputs High SNR: 106dB(A) typ. Near zero pop & click Lead-free 15 bumps, flip-chip package Flip-chip - 15 bumps Pin Connection (top view) VCC2 IN+R Description The TS4985 has been designed for top-class stereo audio applications. Thanks to its compact and power-dissipation efficient flip-chip package, it suits various applications. With a BTL configuration, this audio power amplifier is capable of delivering 1.2W per channel of continuous RMS output power into an 8 load @ 5V. Each output channel (left and right), has an external controlled standby mode pin (STDBYL & STDBYR) to reduce the supply current to less than 10nA per channel. The device also features an internal thermal shutdown protection. The gain of each channel can be configured by external gain setting resistors. ■ ■ ■ ■ VCC1 STDBYL IN-R VO+L VO-L BYPASS VO+R VO-R IN+L GND2 IN-L STDBYR GND1 Applications Cellular mobile phones Notebook & PDA computers LCD monitors & TVs Portable audio devices Order Codes Part Number TS4985EIJT TS4985EKIJT -40, +85°C Temperature Range Package Lead free flip-chip Lead free flip-chip + back coating Packaging Tape & Reel Marking A85 May 2005 Rev 2 1/29 www.st.com 29 Typical Application Schematic TS4985 1 Typical Application Schematic Figu……
