MAX40100
Precision, Low-Power and
Low-Noise Op Amp with RRIO
General Description
The MAX40100 is a low-power, zero-drift operational
amplifier available in a space-saving, 6-bump, wafer-level
package (WLP).
Designed for use in portable consumer, medical, and
industrial applications, the MAX40100 features rail-to-rail
CMOS inputs and outputs, a 1.5MHz GBW at just 66μA
supply current, and 10μV (max) “zero-drift” input voltage
offset over time and temperature.
The zero-drift feature of the MAX40100 reduces the high 1/f
noise typically found in CMOS input operational amplifiers,
making it useful for a wide variety of low-frequency
measurement applications.
The MAX40100 is available in a space-saving, 1.1 x
0.76mm, 6-bump WLP, with 0.35mm bump pitch.
The MAX40100 is specified over the -40°C to +125°C
extended automotive operating temperature range.

board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. 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.
