What is the XD2917-8?

The XD2917-8 is a Xinluda frequency-to-voltage (F/V) and voltage-to-frequency (V/F) converter in an 8-pin DIP package. It belongs to the LM2907/LM2917 family and integrates a tachometer/charge-pump input stage with an op-amp/comparator.

Is the XD2917-8 the same as the LM2917-8?

The XD2917-8 is part of the LM2917-8-compatible family and is intended as a functional equivalent for that standard, making it suitable for legacy LM2917-8 designs. Always confirm pin and electrical compatibility against your application before substituting.

What is the difference between the XD2917-8 and the XL2917-8?

Both are Xinluda 2917-8 frequency/voltage converters. The XD2917-8 is the DIP-8 (through-hole) version, while the XL2917-8 is the SOP-8/SOIC-8 surface-mount version. Per Xinluda, the XD2917-8 is marked end-of-life, while the XL2917-8 remains active.

Is the XD2917-8 still in production?

No. Xinluda has marked the XD2917-8 as end-of-life (EOL/obsolete). Authorized-distributor stock is limited, which is why it is offered on a request-for-quote basis through Pacific Component Xchange.

What package does the XD2917-8 come in?

The XD2917-8 is supplied in an 8-pin DIP (through-hole) package. The surface-mount equivalent is the Xinluda XL2917-8 in SOP-8/SOIC-8.

How do I buy the XD2917-8 if it is obsolete?

Submit a request for quote (RFQ) to Pacific Component Xchange. As an independent distributor specializing in hard-to-find and obsolete components, we will source the XD2917-8 or a verified compatible alternative, confirm authenticity, and quote lead time and pricing for your quantity.

XD2917-8 – Frequency-to-Voltage / Voltage-to-Frequency Converter – Xinluda

The Xinluda XD2917-8 is an LM2917-8-compatible frequency-to-voltage / voltage-to-frequency converter in an 8-pin DIP package, combining a tachometer input stage with an op-amp/comparator. This part is end-of-life and available on a request-for-quote basis.

The XD2917-8 from Xinluda is a monolithic frequency-to-voltage (F/V) and voltage-to-frequency (V/F) converter belonging to the widely used LM2907/LM2917 family. The “-8” designation identifies the 8-pin variant of the device, and the “XD” prefix denotes the through-hole DIP-8 package. It integrates a frequency-sensing input stage (tachometer/charge-pump) with an on-chip op-amp/comparator, making it well suited to building accurate, low-component-count speed sensing, motor control, and frequency-conversion circuits.

Because the XD2917-8 is pin- and function-compatible with the classic LM2917-8, it remains a practical drop-in option for legacy designs and field service of equipment built around that standard. Xinluda has marked the XD2917-8 as end-of-life (EOL), so authorized-distributor stock is scarce and the part is offered on a request-for-quote basis.
