Rated for -40°C to 125°C. The 8-uMAX/uSOP package is a surface-mount MSOP-8 footprint, 3.00 mm wide. Input bias current is 1.6 µA.

Active lifecycle — no LTB risk for new designs

The MAX9928FAUA+ carries an Active lifecycle status and is ROHS3 compliant.

Frequently asked questions

How does MAX9928FAUA+ compare with MAX9929?

The MAX9929 is the bidirectional-output variant of the same current sense amplifier family. The MAX9928FAUA+ provides a unidirectional output referenced to ground, while the MAX9929 outputs a voltage proportional to the magnitude and direction of current flow. Both share the same 150 kHz bandwidth, 20 µA supply current, and 8-uMAX/uSOP package, making them pin-compatible for unidirectional vs bidirectional sensing.
