About this part

The Xinluda XD3916 is a monolithic integrated circuit that senses analog voltage levels and drives a column of ten LEDs, LCDs, or vacuum fluorescent displays, providing an electronic version of the popular VU meter. One pin selectable between a moving-dot or bar-graph display mode, the XD3916 is functionally and pin-compatible with the industry-standard LM3916, making it a practical drop-in for audio VU meters, power meters, and level-indication applications. The device is supplied in an 18-lead plastic dual in-line (DIP-18) package.

Internally, a high-impedance input buffer drives a precision ten-step voltage divider feeding ten comparators, each referenced to a different threshold along the VU scale. The output drive current is regulated and programmable with a single external resistor and the on-chip adjustable reference, eliminating the need for current-limiting resistors on each LED.

Why Source XD3916 from Pacific Component Xchange

The XD3916 is a specialty Xinluda display driver with limited authorized-distributor stock, which can make it difficult to locate in production quantities. Pacific Component Xchange is an independent distributor specializing in hard-to-find and obsolete power-management ICs, display drivers, and optocouplers. We source authentic parts through vetted supply channels, support obsolete and end-of-life sourcing, and ship globally. If you need the XD3916 or a compatible LM3916-class display driver, request a quote (RFQ) and our team will respond with availability, lead time, and pricing.

Frequently asked questions

What is the Xinluda XD3916?

The XD3916 is a monolithic 10-step electronic VU-meter LED bar/dot display driver from Xinluda. It senses an analog voltage and drives ten LEDs, LCDs, or vacuum fluorescent displays on a VU scale, in an 18-lead PDIP package.

Is the XD3916 compatible with the LM3916?

Yes. The XD3916 is functionally and pin-compatible with the industry-standard LM3916 VU-meter display driver and is commonly used as a drop-in alternative in audio VU meters and level-indication circuits. Always confirm against your datasheet for your specific design.

What package does the XD3916 come in?

The XD3916 is supplied in an 18-lead plastic dual in-line package (DIP-18 / PDIP).

Can the XD3916 display in both bar and dot modes?

Yes. A single mode-select pin lets you choose between a bar-graph display (all segments up to the level lit) or a moving-dot display (only the segment at the level lit).

Does the XD3916 need external resistors for the LEDs?

No. The XD3916 has an adjustable on-chip reference and a programmable, current-regulated output (1 mA to 30 mA) set by a single external resistor, so individual LED current-limiting resistors are not required.

How does the XD3916 differ from the XD3914 and XD3915?

All three are pin-compatible 10-step dot/bar display drivers. The XD3914 uses a linear scale, the XD3915 a logarithmic 3 dB/step scale, and the XD3916 a VU-meter scale, matching the LM3914, LM3915, and LM3916 respectively.

How do I buy the XD3916 if it is out of stock elsewhere?

The XD3916 has limited authorized-distributor availability. Pacific Component Xchange sources hard-to-find and obsolete parts like the XD3916 through vetted channels. Submit an RFQ and we will respond with availability, lead time, and pricing.
