TS4985 Datasheet | STMicroelectronics

Description The TS4985 has been designed for top-class stereo audio applications. Thanks to its pact 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 8Ω 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 10n A 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 puters 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 .st.
