Features

* n n n n n n n n n Battery operation Minimum external parts Wide supply voltage range: 4V
* 12V or 5V
* 18V Low quiescent current drain: 4 mA Voltage gains from 20 to 200 Ground referenced input Self-centering output quiescent voltage Low distortion Available in 8 pin MSOP package Applic

Applications

* The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 will increase the gain to any value up to 200. The inputs are ground referenced while the output is automatically biased to one half the supply voltage. The
