Product details

I²C volume control and protection features

The I²C interface allows the host processor to adjust gain in software — no external potentiometer or mechanical volume knob. The part also includes short-circuit and thermal protection, plus a dedicated shutdown pin for low-power standby. These features reduce external component count and improve system reliability in portable products where speaker leads can get shorted during assembly or use.

Not a hand-solder part. The small footprint frees board area for battery or other passives, but the BGA layout demands a multi-layer PCB with via-in-pad or microvias for routing the thermal and power pads.

The TPA2026D2YZHR is an active, in-production part per TI's lifecycle status. ROHS3 compliant.

Frequently asked questions

Does TPA2026D2YZHR support I2C volume control?

Yes, the TPA2026D2YZHR includes an I²C interface for volume control, along with differential inputs, short-circuit and thermal protection, and a shutdown pin.

What is the output power of TPA2026D2YZHR at 4 ohm?
