The XL2917-8 from Xinluda is a monolithic frequency-to-voltage (F/V) converter, functionally equivalent to the industry-standard LM2917-8. It combines a charge-pump tachometer front end with a high-gain operational amplifier output, making it ideal for converting an input frequency or pulse train into a proportional DC voltage. The 8-pin version internally connects the negative comparator input (IN-) to ground and shares the charge-pump output and non-inverting op amp input (CP2/IN+) on a common pin, simplifying tachometer and speed-sensing designs in a compact SOIC-8 footprint.
Output swings to ground for a zero-frequency input, and the charge-pump tachometer offers frequency doubling for low output ripple. The floating-transistor op amp output can drive a ground- or supply-referred load directly, enabling the IC to operate relays, lamps, or other loads when input frequency crosses a programmed threshold.
The XL2917-8 is a specialty Xinluda part with limited authorized-distributor availability, making it difficult to source through mainstream channels. Pacific Component Xchange is an independent distributor specializing in hard-to-find and obsolete power-management ICs, converters, and optocouplers. We help engineers and buyers secure verified, authentic stock for parts that are otherwise unavailable. Whether you need a single prototype quantity or full-reel volumes for production, our team will quote competitively and confirm authenticity, date codes, and lead time. Request a quote (RFQ) today for the XL2917-8 and let our global sourcing network and worldwide shipping get you the components you need.
The XL2917-8 is a Xinluda monolithic frequency-to-voltage (F/V) converter in an SOIC-8 package. It is functionally equivalent to the industry-standard LM2917-8, combining a charge-pump tachometer input with a high-gain operational amplifier output to convert an input frequency into a proportional DC voltage.
The -8 designates the 8-pin version of the device. On the 8-pin part, the charge-pump output and non-inverting op amp input (CP2/IN+) share a pin and the negative comparator input (IN-) is internally connected to ground, simplifying tachometer and speed-sensing circuits.
The XL2917-8 is designed as a functional equivalent of the LM2917-8 frequency-to-voltage converter. As with any cross, verify pinout, electrical limits, and package against the Xinluda datasheet and your circuit requirements before substitution.
The XL2917-8 is supplied in an 8-pin SOIC-8 surface-mount package. It is RoHS compliant with a moisture sensitivity level (MSL) of 3.
Typical uses include motor and fan tachometer speed sensing, frequency-to-voltage conversion in instrumentation, over/under-speed detection, speedometers, and frequency-threshold relay or lamp drivers.
Yes. The XL2917-8 is a hard-to-find Xinluda part with limited mainstream availability. Pacific Component Xchange specializes in sourcing scarce and obsolete components. Submit an RFQ and our team will quote pricing, lead time, and confirm authenticity.
