XD231 – Voltage-to-Frequency / Frequency-to-Voltage Converter – Xinluda

The Xinluda XD231 is a precision voltage-to-frequency / frequency-to-voltage (V/F & F/V) converter in a DIP-8 package, functionally compatible with the industry-standard LM231. Available for RFQ from Pacific Component Xchange.

The Xinluda XD231 is a precision voltage-to-frequency (V/F) and frequency-to-voltage (F/V) converter supplied in a through-hole DIP-8 package. When configured as a V/F converter it produces a pulse train whose output frequency is precisely proportional to the applied input voltage, making it well suited to low-cost analog-to-digital conversion, signal isolation, frequency-based data transmission, and integration tasks. The XD231 is functionally compatible with the long-established LM231 precision voltage-to-frequency converter, providing a drop-in alternative for designs that require this classic function.

Key Features

• Function: precision voltage-to-frequency and frequency-to-voltage converter
• Wide single-supply operation: 4 V to 40 V
• Wide range of full-scale output frequency: 1 Hz to 100 kHz
• Ensured linearity 0.03% maximum
• Temperature stability: 50 ppm/°C (typical)
• Output drives up to 3 TTL loads, or a high-voltage output up to 40 V; short-circuit-proof against VCC
• Low power consumption: approximately 15 mW typical at 5 V
• DIP-8 through-hole package; RoHS compliant
• Functionally compatible with the industry-standard LM231

Applications

• Low-cost analog-to-digital (A/D) conversion
• Frequency modulation and demodulation (FM / V/F telemetry)
• Voltage and current sensor signal conditioning
• Long-line and isolated data transmission over a single wire or optocoupler
• Analog signal integration and precision frequency generation
• Industrial instrumentation and data-acquisition front ends

Why Source XD231 from Pacific Component Xchange

The Xinluda XD231 is a specialty converter IC with limited authorized-distributor availability, which can make it difficult to source through conventional 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 the XD231 and equivalent V/F converters when standard supply lines fall short.

Every order is backed by our commitment to authenticity, careful inspection, and traceable sourcing, with global shipping to keep your production lines and prototypes moving. Because the XD231 is offered on a request-for-quote basis, our team can confirm current availability, lead time, and pricing tailored to your quantity.
