The XL331 from Xinluda (Shenzhen Xinluda Information Technology Co., Ltd.) is a precision voltage-to-frequency (V/F) and frequency-to-voltage (F/V) converter supplied in a compact SOP-8 package. Functionally compatible with the industry-standard LM331 architecture, the XL331 converts an analog input voltage into a proportional pulse-train output frequency, and can also be configured for frequency-to-voltage conversion, making it a versatile building block for data acquisition, isolated signal transmission, and analog-to-digital interfacing.
The XL331 supports split or single-supply operation and can run from a single 5V rail or supplies up to 40V. Its pulse output is compatible with all common logic forms and is short-circuit-proof against VCC, simplifying interfacing to microcontrollers, optocouplers, and counters.
The XL331 is a specialty Xinluda converter IC with limited authorized-distributor coverage, which can make it difficult to procure through mainstream channels. Pacific Component Xchange specializes in sourcing hard-to-find, allocated, and obsolete power-management and signal-conversion components like the XL331. We support open-market and end-of-life sourcing, authenticity verification, and global shipping to keep your production lines and service operations running.
Because the XL331 is offered on a Request-For-Quote basis, pricing and lead time are confirmed at the time of inquiry based on current availability. Submit an RFQ today and our sourcing team will respond with verified stock, pricing, and delivery options for the quantities you need.
The XL331 is a precision voltage-to-frequency (V/F) and frequency-to-voltage (F/V) converter from Xinluda, supplied in an SOP-8 package. It converts an analog input voltage into a proportional output pulse frequency (and vice versa), and is functionally compatible with the classic LM331 architecture.
The XL331 is offered in a standard 8-pin small-outline package (SOP-8).
The XL331 operates over a 4V to 40V supply range and runs on a single 5V supply. Its full-scale output frequency range spans 1 Hz to 100 kHz with 0.03% maximum linearity.
Yes. The XL331 supports both voltage-to-frequency conversion (for ADC front ends, telemetry, and signal transmission) and frequency-to-voltage conversion (for tachometer and speed-sensing applications).
The XL331 is a hard-to-find Request-For-Quote (RFQ) item with limited authorized-distributor stock. Pacific Component Xchange sources it on the open market; submit an RFQ and our team will confirm current availability, pricing, and lead time.
Pacific Component Xchange specializes in hard-to-find and allocated signal-conversion and power-management ICs like the XL331. We provide authenticity verification, open-market and end-of-life sourcing, and global shipping when the part is not readily available through mainstream channels.
