EVALUATION KIT AVAILABLE

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

General 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.
