TS4994FC 1.2 W 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 1.2W 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 9-bump flip-chip (300mm bump diameter) Lead-free package TS4994EIJT - Flip-chip (9 bumps) Gnd VOBypass VIN+ 7 6 5 VO+ Stdby VIN- 8 1 9 2 VCC 4 3 Stdby Mode The device is equipped with common mode feedback circuitry allowing outputs to be always biased at VCC/2 regardless of the input common mode voltage. The TS4994 is designed for high quality audio applications such as mobile phones and requires few external components. 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. An internal thermal shutdown protection is also provided, making the device capable of sustaining short-circuits.
