Product Details

Top Features

  • User-controlled sleep mode with fast (< 60 µs) wakeup time for lag-free power savings
  • 3.2 mA active and 25 µA sleep current reduces total power consumption and extends battery life
  • Operates down to 2.5 V supply for battery applications
  • Low quiescent voltage output maximizes output range and resolution
  • Small size DFN-6 (2 mm x 3 mm x 0.75 mm) for minimal board area
