LM2907N DIP-14 Voltage Frequency Converter IC

The LM2907 and LM2917 devices are monolithic frequency-to-voltage converters with a high-gain op amp designed to drive a relay, lamp, or other load when the input frequency reaches or exceeds a selected ratio.

The op amp is fully compatible with the tachometer and has a floating transistor as its output. This feature allows ground or supply source load up to 50 mA. The collector can be taken above VCC up to a maximum of 28 V VCE.
