MAX40100 Precision, Low-Power and Low-Noise Op Amp with RRIO General Description Benefits and Features The MAX40100 is a low-power, zero-drift operational am- Low 66A Quiescent Current plifier available in a space-saving, 6-bump, wafer-level Low Input Noise: package (WLP). 42nV/Hz at 1kHz 0.42V from 0.1Hz to 10Hz P-P Designed for use in portable consumer, medical, and in- dustrial applications, the MAX40100 features rail-to-rail Rail-to-Rail Inputs and Outputs (RRIO) CMOS inputs and outputs, a 1.5MHz GBW at just 66A 1.5MHz GBW supply current, and 10V (max) zero-drift input voltage Ultra-Low 10pA Input Bias Current offset over time and temperature. Single 1.6V to 5.5V Supply Voltage Range Unity Gain Stable The zero-drift feature of the MAX40100 reduces the high Power-Saving Shutdown Mode 1/f noise typically found in CMOS input operational ampli- Tiny, 1.1mm x 0.76mm, 6-bump WLP fiers, making it useful for a wide variety of low-frequency measurement applications. Ordering Information appears at end of data sheet. 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 -40C to +125C ex- tended automotive operating temperature range.

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.
