The MAX9700DEUB+: It is ROHS3 compliant, so it meets the latest EU restriction-of-hazardous-substances directive without an exemption.
Package and board-fit considerations
Housed in a 10-lead TFSOP/MSOP package (3.00 mm body width), the supplier device package is designated 10-uMAX/uSOP — a common footprint for space-constrained portable audio. The surface-mount package suits automated assembly; the 0.50 mm lead pitch requires a standard fine-pitch solder profile.
Protection and input features
On-chip protection includes short-circuit and thermal shutdown, so the amplifier survives a momentary output short or sustained high-power operation without external clamp diodes. Differential inputs reject common-mode noise picked up on the audio trace between the codec and the amplifier — useful when the routing crosses a noisy digital section. A depop (pop-and-click suppression) circuit mutes the output during power-up and shutdown, eliminating the audible thump that otherwise couples into the speaker.
