Product details

Package and mounting — 16-TQFN with exposed pad

The MAX4740ETE+T comes in a 16-lead TQFN (3x3mm) with an exposed pad. The pad must be soldered to a PCB thermal land — it provides the primary heat path for the device. The part is rated for surface-mount assembly and ships on Tape & Reel (or Cut Tape for prototyping). The small footprint suits space-constrained audio boards in portable or embedded equipment.

Lifecycle and sourcing — active, no obsolescence pressure

The MAX4740ETE+T is listed as Active with ROHS3 compliance. There is no last-time-buy notice or NRND flag. For new designs, this is a safe selection with no near-term end-of-life risk.

Frequently asked questions

What is the on-resistance of MAX4740ETE+T?

The maximum on-resistance is 900mOhm. This low value minimizes signal loss and distortion in audio paths.

What package does MAX4740ETE+T use?

It uses a 16-TQFN (3x3mm) package with an exposed pad, supplier device package 16-TQFN. It also ships in Tape & Reel or Cut Tape.

What is MAX4740ETE+T's listed applications?

The listed application is Audio. The low on-resistance and wide supply range suit it for headphone, line-level, and microphone switching.
