XD3140 – Operational Amplifier – Xinluda

The Xinluda XD3140 is an operational amplifier from the Xinluda XD analog series, offered as a CA3140-type BiMOS op-amp equivalent. Pacific Component Xchange sources this hard-to-find part on a request-for-quote basis.

The Xinluda XD3140 is an operational amplifier manufactured by Xinluda Information Technology Co., Ltd., a Chinese semiconductor company (R&D in Xiamen, sales in Shenzhen) whose analog catalog includes universal, precision, high-speed and transconductance operational amplifiers, comparators, LED/lighting drivers, power-management ICs and other analog devices. The XD3140 sits within Xinluda’s XD op-amp range and is marketed as a drop-in equivalent for the classic CA3140-type BiMOS operational amplifier (MOSFET input / bipolar output architecture). It is an uncommon part that does not appear in mainstream authorized-distributor inventory and is offered by Pacific Component Xchange on a request-for-quote basis.

Because the XD3140 is a scarce, hard-to-source device and Xinluda does not publish a widely mirrored standalone XD3140 datasheet, exact electrical ratings should be confirmed before purchase. Our sourcing team can verify the precise device variant, package, marking, date code, and datasheet parameters as part of your quote so you receive exactly the part your build requires rather than unconfirmed figures.

Key Features

• Manufacturer: Xinluda Information Technology Co., Ltd.
• Device class: operational amplifier (analog/linear)
