MAX40108 1V, Low-Power, Precision Operational Amplifier General Description Benefits and Features The MAX40108 is a low-power, high-precision operational amplifier (op amp) that operates with a power supply voltage as low as 0.9V. ● ● ● ● ● ● ● ● ● Available in a space-saving, 1.22mmx 0.92mm, 6-bump wafer-level package (WLP) with a 0.4mm bump pitch, it is designed for use in portable, consumer, medical, and industrial applications. The MAX40108 features rail-to-rail CMOS inputs and outputs, a 168kHz GBW consuming only 25.5µA (typ) supply current and 1µV (typ) zero-drift input offset voltage over time and temperature. The zero-drift feature 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 MAX40108 operates from a 0.9V to 3.6V power supply voltage and is specified over the -40°C to +125°C extended operating temperature range. Applications ● Wearable Devices ● Home Medical (Blood Glucose,Weight Scale, Blood Pressure, EKG) ● Fitness and Health (Smart Watch, Heart-Rate Monitor) ● Industrial IOT (Pressure, Flow, Level, Temperature, Proximity) Typical Application Circuit 19-100763; Rev 0; 7/20 Supply Voltage Range: 0.9V to 3.6V Low 25.5μA Quiescent Current Very Low 1μV (typ) Input Offset Voltage Rail-to-Rail Inputs and Outputs Internal EMI Rejection 168kHz GBW Low Input Bias Current Power-Saving Shutdown Mode Available in Tiny, 1.22mm x 0.92mm, 6-bump WLP and 8-pin TDFN Ordering Information appears at end of
