1 / 30 page  Rev 2 November 2005 1/30 30 TS4984FC 1.2W Stereo Audio Power Amplifier with Active Low Standby Mode ■ Operating from VCC = 2.2V to 5.5V ■ 1.2W output power per channel @ VCC =5V, THD+N = 1%, RL =8Ω ■ 10nA standby current ■ 62dB PSRR @ 217Hz with grounded inputs ■ High SNR: 106dB(A) typ. ■ Near-zero pop & click ■ Available in a 15-bump flip-chip (lead-free) Description The TS4984 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 output BTL configuration, this audio power amplifier is capable of delivering 1.2W per channel of continuous RMS output power into an 8 Ω load @ 5V. An externally-controlled standby mode reduces 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. Applications ■ Cellular mobile phones ■ Notebook & PDA computers ■ LCD monitors & TVs ■ Portable audio devices Order Codes TS4984 - flip-chip 15 bumps Pin connections (top view) VCC IN2+ VCC BYPASS IN2- VOUT1+ STDBY VOUT2+ VOUT2- VOUT1- IN1+ GND GND BYPASS IN1- VCC IN2+ VCC BYPASS IN2- VOUT1+ STDBY VOUT2+ VOUT2- VOUT1- IN1+ GND GND BYPASS IN1- Part Number Temperature Range Package Packing Marking TS4984EIJT -40, +85°C Lead free flip-chip Tape & Reel A84 TS4984EIKJT Lead free flip-chip + back coating www.st.com |
