The – 5.7 W at 1% THD+N and 6.9 W at 10% device features a ultra low-noise audio DAC and THD+N into 4- Ω Load from 4.2-V Supply Class-D power amplifier which incorporates speaker – 3.8 W at 1% THD+N and 4.5 W at 10% voltage and current sensing feedback. An on-chip, low-latency DSP supports Texas Instruments THD+N into 8- Ω Load from 4.2-V Supply SmartAmp speaker protection algorithms to • Output Noise for DAC + Class-D(ICN) is 15.9 µV maximizes loudness while maintaining safe speaker • DAC + Class-D SNR 111 dB at 1%THD+N/8 Ω conditions. • THD+N –90 dB at 1 W / 8 Ω with Flat Frequency The device can be used easily with any processor Response with an I2S output and stereo implementations are • PSRR 110 dB for 200 mVpp ripple at 217 Hz possible when using two TAS2555 devices. Separate tuning for different speakers is supported allowing • Input Sample Rates from 8 kHz to 96 kHz customers to add value while maintaining form factor • Built-In Speaker Sense designs. Additionally, the TAS2555 supports separate – Measures Speaker Current and Voltage voice and audio tuning dynamically with ultra-low 15.9 – Measures VBAT Voltage, Chip Temperature µV ICN regardless of mode of operation making receiver/speaker implementations possible. • Dedicated Real-Time DSP for Speaker Protection A Class-H boost converter generates the Class-D – Thermal and Excursion Protection amplifier supply rail. When the audio signal only – Detects Leak and Damaged Speaker requires a lower Class-D output power, the boost • High Efficiency Class-H Boost Converter With improves system efficiency by deactivating and Multi-Level Tracking connecting VBAT directly to the Class-D amplifier supply. When higher audio output power is required, – 86% at 500 mW in 8 Ω with 3.6 V VBAT the multi-level boost quickly activates tracking the – 87% at 700 mW in 8 Ω with 4.2 V VBAT signal to provide the additional voltage to the load. • Built-In Automatic Gain Control (AGC) – Limits Battery Current Consumption Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) • Adjustable Class-D Switching Edge-Rate Control TAS2555 WCSP (42) 3.47 mm x 3.23 mm • Power Supplies (1) For all available packages, see the orderable addendum at – Boost Input: 2.9 V to 5.5 V the end of the data sheet. – Analog/Digital: 1.65 V to 1.95 V – Digital I/O: 1.62 V to 3.6 V Simplified Schematic • Thermal, Short-Circuit, and Under-Voltage Protection • I2S, Left-Justified, Right-Justified, DSP, and TDM Input and Output Interface, • I2C or SPI Interface for Register Control • 3.47 mm x 3.23 mm, 0.5 mm pitch, 42-ball WCSP • Stereo Configuration Using Two TAS2555 Devices 2 Applications • Mobile Phones • Tablets • Portable Audio Docks • Bluetooth Speakers 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
