XD331 – Voltage-to-Frequency / Frequency-to-Voltage Converter – Xinluda

The Xinluda XD331 is a precision voltage-to-frequency and frequency-to-voltage (V/F, F/V) converter in a DIP-8 package, functionally aligned with the industry-standard LM331. Available for quote at Pacific Component Xchange.

The Xinluda XD331 is a precision voltage-to-frequency (V/F) and frequency-to-voltage (F/V) converter supplied in an 8-pin DIP package. Part of Xinluda’s LM331-type analog converter family, the XD331 produces an output pulse-train frequency that is highly linear with the applied input voltage, making it well suited to low-cost analog-to-digital conversion, signal isolation, and precision measurement tasks. It shares its core architecture and pinout with the widely used LM331 standard.

Key Features

• Precision voltage-to-frequency (V/F) and frequency-to-voltage (F/V) conversion
• Ensured linearity of ±0.03% maximum
• Full-scale frequency range up to 100 kHz
• Wide single-supply operating range of 4 V to 40 V
• Low power consumption, approximately 15 mW typical at 5 V
• Temperature stability on the order of 50 ppm/°C
• LM331-type pin-compatible architecture in an 8-pin DIP package

Applications

• Low-cost analog-to-digital (A/D) conversion
• Frequency-to-voltage decoding and tachometer/RPM readout
• Analog signal transmission over isolated or noisy links
• Precision long-term integration and data acquisition
• Voltage-controlled oscillators and FM signal generation

Why Source XD331 from Pacific Component Xchange

The Xinluda XD331 is a specialty analog converter with limited authorized-distributor availability, which can make it difficult to source through mainstream channels. Pacific Component Xchange is an independent distributor focused on hard-to-find and obsolete power-management and analog ICs. We help engineers and buyers secure niche parts like the XD331 when conventional supply lines fall short.

Every order is backed by our commitment to authenticity and quality, with inspection processes designed to protect you against counterfeit and substandard components. We support global shipping and flexible quantities for both prototype and production needs. Because the XD331 is offered on a request-for-quote basis, contact Pacific Component Xchange for current pricing, lead time, and availability — submit an RFQ today and our sourcing team will respond promptly.
