The MAX9700CEBC-T is a Maxim Integrated Class D audio amplifier delivering 1.6 W into a 6 Ω load from a single mono channel. That output power is specified at the load impedance, so a designer sizing this for a portable speaker or a small alarm tone generator knows the headroom into a typical 6 Ω mini-speaker.
CSP footprint — 2.02 x 1.54 mm body
The part is offered in a 10-WFBGA / CSPBGA package with a supplier device package of 12-UCSP measuring 2.02 x 1.54 mm.
RoHS non-compliant — compliance flag for EU markets
However, it is listed as RoHS non-compliant. That is the single most important sourcing constraint: any BOM destined for European Union markets or other RoHS-regulated jurisdictions cannot use this part in new product introductions.
