TS4994

TS4994 1W differential input/output audio power amplifier with selectable standby Features ■ Differential inputs ■ Near-zero pop & click ■ 100dB PSRR @ 217Hz with grounded inputs ■ Operating range from VCC = 2.5V to 5.5V ■ 1W rail-to-rail output power @ VCC = 5V, THD = 1%, F = 1kHz, with 8Ω load ■ 90dB CMRR @ 217Hz ■ Ultra-low consumption in standby mode (10nA) ■ Selectable standby mode (active low or active high) ■ Ultra fast startup time: 15ms typ. ■ Available in DFN10 3x3 (0.5mm pitch) & MiniSO-8 ■ All lead-free packages Description The TS4994 is an audio power amplifier capable of delivering 1W of continuous RMS output power into an 8Ω load @ 5V. Due to its differential inputs, it exhibits outstanding noise immunity. An external standby mode control reduces the supply current to less than 10nA. An STBY MODE pin allows the standby to be active HIGH or LOW (except in the MiniSO-8 version). An internal thermal shutdown protection is also provided, making the d...
