  • V+ to positive supply (2.7V to 36V)
  • GND to ground
  • Input signal to non-inverting input
  • Feedback network for desired gain

Single-Supply Biasing

For AC-coupled single-supply circuits:

  • Bias non-inverting input to mid-supply voltage
  • Use coupling capacitors on inputs/outputs
  • Allows full dynamic range utilization

Notes

Versatile dual op-amps for single-supply applications. The wide 2.7V to 36V supply range makes these excellent for battery-powered projects and diverse analog circuit designs. Stock of 8 units provides good supply for multiple projects. Note that these are surface-mount components (VSSOP-8 package), so they may require a breakout board or careful SMD soldering for prototyping use.
