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

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 no inverting 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_DDto 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.
