... The LMV921/LMV922/LMV924’s high DC gain of 100dB makes them suitable for low frequency applications. The LMV921 (Single) is offered in a space saving SC70–5 and SOT23–5 packages. The SC70–5 package is only 2.0X2.1X1.0mm. These small packages are ideal solutions for area constrained PC boards and portable electronics such as cellphones and PDAs ...

... Typical Applications 1.0 Half-wave Rectifier with Rail-To-Ground Output Swing Since the LMV921 input common mode range includes both positive and negative supply rails and the output can also swing to either supply, achieving half-wave rectifier functions in either direction is an easy task. All that is needed are two external resistors ...
