MAX44281 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.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Package Thermal Characteristics (Note 1) WLP Junction-to-Ambient Thermal Resistance (θJA).........103°C/W Note 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.
