Features and Benefits
- Ultra-Low 800nA per Amplifier Supply Current
- Ultra-Low 1.4V Supply Voltage Operation (1.8V for MAX4037/MAX4039)
- Rail-to-Rail Outputs Drive 5kΩ and 5000pF Load
- 1.232V ±0.5%, 120ppm/°C (max) Reference (MAX4037/MAX4039)
- No External Reference Bypass Capacitor Required
- No Phase Reversal for Overdriven Inputs
- Low 1.0pA (typ) Input Bias Current
- Low 200µV Input Offset Voltage
- Unity-Gain Stable
- Available in Tiny UCSP, SC70, SOT23, TDFN, and µMAX Packages
- Available in -40°C to +125°C Temperature Range (MAX4036A/MAX4038A)
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 800nA of supply current per amplifier, and 1.1µA for the optional reference. The MAX4036/MAX4038 feature a common-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 25mV 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 NiCd/NiMH/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.
