این آی سی یک نوع مدل فرکانس به ولتاژ میباشد پکیج این آی سی از نوع DIP بوده و دارای 8 پایه است

 The LM2907, LM2917 series are monolithic frequency to voltage converters with a high gain op amp/comparator de signed to operate a relay, lamp, or other load when the input frequency reaches or exceeds a selected rate. The tachom eter uses a charge pump technique and offers frequency doubling for low ripple, full input protection in two versions (LM2907-8, LM2917-8) and its output swings to ground for a zero frequency input.
