The Xinluda XD2917-14 is a monolithic frequency-to-voltage (F/V) converter supplied in a 14-pin DIP package. It belongs to the well-established LM2907/LM2917 family and is the Xinluda equivalent of the industry-standard LM2917-14, making it a practical alternative for tachometer, speed-sensing, and frequency-detection circuits. The “17” designation (as opposed to the LM2907/XD2907) indicates the inclusion of an on-chip zener shunt regulator, allowing stable frequency-to-voltage and frequency-to-current operation from an unregulated supply with only a single series resistor.
The device combines a charge-pump tachometer input stage with a high-gain op amp/comparator. The tachometer uses a frequency-doubling charge-pump technique to deliver low-ripple output and full input protection, and the output swings to ground for a zero-frequency input. The op amp/comparator features a floating transistor output capable of driving relays, lamps, or other loads when the input frequency reaches or exceeds a user-selected threshold. The 14-pin version brings out additional internal connections compared with the 8-pin part, giving designers access to a differential tachometer input and the op amp inputs for greater application flexibility.
The Xinluda XD2917-14 is an end-of-life (EOL) part with little to no authorized-distributor stock, which can stall production for designs that depend on this specific F/V converter. Pacific Component Xchange specializes in hard-to-find and obsolete power-management and signal-conditioning ICs, helping engineers and buyers secure parts that mainline distributors no longer carry. We support authenticity-focused sourcing, flexible quantities, and global shipping. Request a quote (RFQ) for the XD2917-14 today and our sourcing team will respond with availability, lead time, and pricing. Contact Pacific Component Xchange to lock in supply for your tachometer and frequency-sensing builds.
It is a monolithic 14-pin DIP frequency-to-voltage (F/V) converter from the LM2907/LM2917 family. It pairs a charge-pump tachometer input with a high-gain op amp/comparator and is used to convert an input frequency into a proportional output voltage for speed-sensing and frequency-detection applications.
It is the Xinluda equivalent of the industry-standard LM2917-14 frequency-to-voltage converter and is generally suitable as an alternative. Always confirm electrical parameters against the datasheet for your specific design before substitution, as the Xinluda datasheet specifies a -25 C to +85 C civil-grade temperature range.
The XD2917 (LM2917-type) includes an on-chip zener shunt regulator (typ. 7.56 V), allowing operation from an unregulated supply with a single series resistor, while the XD2907 (LM2907-type) omits the internal regulator. Both share the same charge-pump tachometer and op amp/comparator core.
The XD2917-14 is supplied in a 14-pin DIP (dual in-line) through-hole package. Xinluda also offered the 8-pin DIP version (XD2917-8) and an 8-pin SOP version (XL2917-8).
No. Xinluda lists the XD2917-14 as end-of-life (EOL), so it is no longer in active production and has little to no authorized-distributor stock. Pacific Component Xchange can help source remaining inventory - submit an RFQ for availability.
Common uses include motor and engine tachometer/RPM sensing, speed governors, over- and under-speed detection, magnetic-pickup signal conditioning, frequency switching, and motion or proximity detection in automotive and industrial systems.
The XD2917-14 is an EOL part with little to no authorized-distributor stock, so it can be difficult to source through mainline channels. Pacific Component Xchange specializes in hard-to-find and obsolete ICs - submit an RFQ and our team will provide availability, lead time, and pricing.
