TS488(2019) Datasheet - STMicroelectronics

Description
The TS488 is a dual audio power amplifier capable of driving, in single-ended mode, either a 16 Ω or a 32 Ω stereo headset.
The TS488 eliminates pop and click noise and reduces the number of required external passive components.

FEATUREs
• Pop and click noise protection circuitry
• Operating range from VCC = 2.2 V to 5.5 V
• Standby mode active low
• Output power:
    – 120 mW at 5 V, into 16 Ω with 0.1% THD+N max. (1 kHz)
    – 55 mW at 3.3 V, into 16 Ω with 0.1% THD+N max. (1 kHz)
• Low current consumption: 2.7 mA max. at 5 V
• Ultra-low standby current consumption: 10 nA typical
• High signal-to-noise ratio
• High crosstalk immunity: 102 dB (F = 1 kHz)
• PSRR: 70 dB typ. (F = 1 kHz), inputs grounded at 5 V
• Unity-gain stable
• Short-circuit protection circuitry
• Available in DFN8 2x2 mm

APPLICATIONs
• Headphone amplifiers
• Mobile phones, PDAs, computer motherboards
• High-end TVs, portable audio players
