Frequently Asked Questions
What output power and audio bandwidth does the TS4997IQT deliver?
The TS4997IQT provides 1 W nominal output power per channel across a 20 kHz audio bandwidth with only 1% harmonic distortion, making it suitable for high-fidelity stereo playback in consumer devices.
Which package does the TS4997IQT use and how does it benefit compact PCB designs?
The TS4997IQT comes in a 16-pin QFN (S-XQCC-N16) leadless package, which minimizes board footprint and improves thermal performance compared to leaded packages, ideal for space-constrained portable audio applications.
Is the TS4997IQT compatible with RoHS requirements for lead-free assembly?
Yes, the TS4997IQT carries JESD-609 Code e3 and is marked Pb-free, fully compliant with RoHS directives. This means it can be processed through standard lead-free reflow soldering profiles at temperatures up to 260°C.
How many channels does the TS4997IQT support and what consumer applications can it target?
The TS4997IQT integrates 2 audio channels with a 3D stereo enhancement function. This makes it a strong fit for portable speakers, tablets, and wearables where 2-channel, 1 W per channel amplification is needed in a single IC.
