The XD2907-8 is a monolithic frequency-to-voltage (F/V) and voltage-to-frequency (V/F) converter from Xinluda, supplied in an 8-pin package and functionally equivalent to the widely used LM2907-8. It integrates a charge-pump tachometer with frequency doubling for low output ripple, plus a high-gain op amp/comparator with a floating transistor output capable of driving a relay, lamp, solenoid, meter, or LED directly. The output swings to ground for a zero-frequency input, and the device is well suited to single-speed or frequency-switching and fully buffered frequency-to-voltage conversion.
In the 8-pin XD2907-8 / LM2907-8 configuration, the tachometer input is ground-referenced: the negative terminal of the input comparator is internally connected to ground, so an input signal must swing above and below ground to trigger the output. This makes the device ideal for interfacing directly with variable-reluctance magnetic pickups, which produce a single-ended AC signal. The ground-referenced input is robustly protected against input swings beyond the supply rails.
The XD2907-8 is a specialty Xinluda device with little to no authorized-distributor stock, making it difficult to obtain through conventional channels. Pacific Component Xchange is an independent distributor specializing in hard-to-find and obsolete power-management ICs, analog converters, and optocouplers. We source the XD2907-8 through a vetted global supply network with a focus on authenticity and traceability, and we ship worldwide to support your production and maintenance needs.
Whether you need a single prototype quantity or a full production run of the XD2907-8, our sourcing team can help. Request a quote (RFQ) today and our specialists will respond promptly with availability, lead time, and pricing for this hard-to-find frequency-to-voltage converter.
The XD2907-8 is an 8-pin monolithic frequency-to-voltage (F/V) converter from Xinluda. It is functionally equivalent to the industry-standard LM2907-8 and integrates a charge-pump tachometer with a high-gain op amp/comparator and a floating transistor output for tachometer and speed-sensing applications.
Yes. The Xinluda XD2907-8 is built to the LM2907-8 specification, sharing the same 8-pin pinout, ground-referenced tachometer input, charge-pump frequency-doubling architecture, and 50 mA floating-transistor output. Always confirm critical parameters against the datasheet for your specific design.
The 8-pin XD2907-8 has a ground-referenced tachometer input (one comparator input internally tied to ground) and an internal connection between the tachometer output and the op amp input, making it ideal for single-speed switching and buffered F/V conversion. The 14-pin XD2907-14 offers a differential tachometer input and uncommitted op amp inputs for more versatile active-filter conditioning.
No. As with the LM2907 family, the 8-pin '2907' variant does not include the on-chip zener regulator. The zener-regulated version is the LM2917 (e.g., XL2917-8), which clamps the supply for stable frequency-to-voltage and frequency-to-current operation across a range of supply voltages.
Typical applications include tachometers, speedometers, engine RPM measurement, over-speed and under-speed sensing, cruise control, speed governors, breaker-point dwell meters, and touch or sound-activated switches. Its ground-referenced input is especially suited to variable-reluctance magnetic pickups.
The XD2907-8 is a hard-to-find specialty part. Pacific Component Xchange sources it through a vetted global supply network with a focus on authenticity and traceability. Submit a Request for Quote (RFQ) and our team will respond with availability, lead time, and pricing.
