Product Overview
The TAS2562 is a Texas Instruments boosted Class-D audio amplifier for Signal_Chain designs requiring digital audio input, boost-assisted output drive, and compact packaging. The device supports 8 kHz to 192 kHz digital audio interface operation and 8-channel I2S/TDM support at 32-bit, 96 kHz. Four selectable I2C addresses using AD0 and AD1 pins allow up to four devices on a common I2S/TDM and I2C bus.
Output capability includes 6.1 W into a 4 ohm load and 5 W into an 8 ohm load at 1% THD+N with VBAT=3.6 V. With external PVDD operation, the maximum continuous output power is specified as 10.4 W into 4 ohm + 33 uH at 1% THD+N and 1 kHz. Audio performance parameters include 15 uVrms A-weighted idle channel noise, 112.5 dB SNR, 109 dB dynamic range, 110 dB mute attenuation, and 0.01% internal boost THD+N at 1 W.
The package is a 36-ball DSBGA with 0.4 mm pitch and a 2.41 mm x 2.43 mm nominal body. Recommended supplies are 2.7 V to 5.5 V on VBAT and 1.65 V to 1.95 V on VDD. Thermal and rating data include 55.3°C/W junction-to-ambient thermal resistance, -40°C to 85°C free-air operating temperature, and -40°C to 150°C operating junction temperature.

Procurement Notes
When requesting a quote for TAS2562, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
