Product details

Protection features and shutdown control

Short-circuit and thermal protection are on-die — no external clamp diode or PTC needed. The shutdown pin lets a GPIO or a codec headphone-detect line pull the amp into low-power mode; quiescent current in shutdown is under 1 µA (typical), which matters for battery standby budgets. The depop circuit ramps the output bias slowly, so no audible pop on enable.

The TPA2034D1YZFT is an active, current-production part with ROHS3 compliance. No last-time-buy or end-of-life notices are present.

Frequently asked questions

What is the TPA2034D1YZFT output power?

The TPA2034D1YZFT delivers 2.75W into a 4Ω load at 5V supply, 10% THD+N. At 1% THD+N the output is approximately 1.7W into 4Ω.

Is TPA2034D1YZFT lead-free?

Yes, the TPA2034D1YZFT is ROHS3 compliant, meaning it meets the EU lead-free directive.

TPA2034D1YZFT vs TPA2035D1 — what is the difference?

The TPA2035D1 is a pin-compatible sibling with a higher output power rating (3.2W into 4Ω at 5V, 10% THD). If the BOM needs more headroom for a larger speaker, the TPA2035D1 is the drop-in upgrade; the TPA2034D1 fits when the 2.75W ceiling is sufficient and the slightly lower supply current matters.

What is the typical application for TPA2034D1YZFT?

This Class D amp is designed for portable battery-powered devices: smartphones, tablets, portable speakers, and gaming consoles where board space is tight and a mono speaker channel is needed.
