EVALUATION KIT AVAILABLE
MAX44281
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 (A_V) 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
V_DD to ground. During shutdown, both the input and the
output are high impedance.
The device is available in an ultra-small, 0.86mm x
0.86mm, 4-bump WLP package with 0.5mm height. It is
specified over the -40°C to +125°C temperature range.
