TAS2764YBHR

Overview

The TAS2764YBHR is a mono digital input Class-D audio amplifier with speaker IV sense. It delivers 13 W into 4 Ω and 8 W into 8 Ω at 12 V supply. PVDD operates from 2.3 V to 16 V, while VBAT1S ranges from 2.3 V to 5.5 V. AVDD is 1.8 V and IOVDD supports 1.2 V or 1.8 V. The device features Y-Bridge architecture, edge/spread spectrum control, and ultrasonic output up to 40 kHz. It includes integrated speaker voltage/current sense, short/open detection, thermal/over-current protection, and I2C/I2S/TDM interfaces.

Feature Summary

• Y-Bridge power architecture improves efficiency at low output power levels.
• Integrated speaker voltage and current sense enables real-time monitoring of loudspeaker behavior.
• Supports advanced ultrasonic applications such as motion and proximity detection.
• Brownout prevention scheme reduces gain when supply voltage drops.

Applications

• Laptop Computers
• Tablets
• Wireless Speakers
• Smart Speakers
• Consumer Audio Devices
