Procurement Notes

Verify the specific suffix 'EIJT' to confirm the 18-ball FlipChip package and tape-and-reel delivery format. Ensure compatibility with the target PCB footprint and thermal requirements associated with this small outline package. Cross-reference the manufacturer's latest datasheet for any updates on environmental compliance or pinout definitions before finalizing procurement.

Selection Notes

Select this component when a single-channel mono amplifier is required for battery-powered devices. It is suitable for applications needing moderate power output into low impedances like 8-ohm speakers. Consider the physical size constraints of the 18-ball FlipChip package during layout. This part is distinct from other TS48xx series variants that may offer different power levels or packaging options.

Part Context

This component belongs to STMicroelectronics' portfolio of integrated audio amplifiers designed for portable electronics. It addresses the need for space-saving solutions in modern mobile devices where board real estate is limited. The integration level reduces external component count compared to discrete amplifier designs.
