Frequency to Voltage Converter, available under LM2907 and LM2917 series are monolithic frequency to voltage converters with a high gain op amp/comparator designed to operate a relay, lamp, or other load when the input frequency reaches or exceeds a selected rate. The tachometer 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. Frequency to Voltage Converter is offered by National Semiconductors India Designs Pvt Ltd.
National Semiconductors India Designs Pvt Ltd, a wholly owned subsidiary of California-based National Semiconductor, manufactures and supplies innovative analog technology products that are energy-efficient and easy-to-use, with particular expertise in ultra low power designs. Frequency to Voltage Converter is fully compatible with the tachometer and has a floating transistor as its output. This feature allows either a ground or supply referred load of up to 50 mA. The collector may be taken above VCC up to a maximum VCE of 28V.
