MAX4037 Datasheet | Maxim Integrated

Description The single MAX4036/MAX4037 and dual MAX4038/ MAX4039 operational amplifiers operate from a single +1.4V to +3.6V (without reference) or +1.8V to +3.6V (with reference) supply and consume only 800n A of supply current per amplifier, and 1.1µA for the optional reference. The MAX4036/MAX4038 feature a mon-mode input voltage range from 0V to VDD - 0.4V at VDD = 1.4V. The MAX4037/MAX4039 feature a 1.232V voltage reference capable of sourcing 100µA and sinking 20µA. The MAX4036- MAX4039s’ rail-to-rail outputs drive 5kΩ loads to within 25m V of the rails. Ultra-low supply current, low operating voltage, and rail-to-rail outputs make the MAX4036- MAX4039 ideal for use in single-cell lithium-ion (Li+), or two-cell Ni Cd/Ni MH/alkaline battery-powered applications. The MAX4036 is available in an SC70 package, the MAX4037 in a SOT23 package, and the MAX4038/ MAX4039 in UCSP™, µMAX®, and TDFN packages. All devices are specified over the -40°C to +85°C extended temperature range. Features -...
