MAX44281

Ultra-Small, Ultra-Thin, 4-Bump Op Amp

Industry's Smallest and Thinnest Op Amp (0.9mm x 0.9mm x 0.5mm)


Please check latest availability status for a specific part variant.

Description

The MAX44281 is the industry's first op amp in a 4-bump WLP package, designed for use in portable consumer and medical applications. This device is offered as a noninverting amplifier with gain (AV) of +1V/V, +2V/V, or +10V/V.

The device features rail-to-rail output, low 100µV input voltage offset, and 15MHz of bandwidth with only 700µA of supply current.

The device features shutdown functionality by pulling VDD to ground. During shutdown, both the input and the output are high impedance.

The device is available in an ultra-small, 0.85mm x 0.85mm, 4-bump WLP package with 0.5mm height. It is specified over the -40°C to +125°C temperature range.
