XD7135 – 4 1/2-Digit Precision Analog-to-Digital Converter (ADC) – Xinluda

The Xinluda XD7135 is a 4 1/2-digit precision analog-to-digital converter (ADC) with multiplexed BCD outputs in a DIP-28 package, functionally equivalent to the classic ICL7135 dual-slope integrating converter.

The Xinluda XD7135 is a 4 1/2-digit precision analog-to-digital converter (ADC) that uses dual-slope integrating conversion to deliver high-accuracy, low-drift measurement. It is a pin- and function-compatible alternative to the industry-standard ICL7135-class converter and is supplied in a through-hole DIP-28 package. With multiplexed BCD digit outputs, the XD7135 interfaces easily to external display drivers, microprocessors, and counters, making it a workhorse part for digital panel meters (DPM), digital voltmeters (DVM), and precision instrumentation.

Key Features

• 4 1/2-digit precision analog-to-digital conversion
• Dual-slope integrating architecture for high noise rejection and stability
• Multiplexed BCD outputs with digit-driver lines for straightforward display interfacing
• Single analog input channel
• Analog input voltage range of approximately -8 V to 6 V
• Conversion/sample rate up to 1000 SPS
• Through-hole DIP-28 package
• ICL7135-compatible footprint and function for drop-in replacement

Applications

• Digital panel meters (DPM) and digital voltmeters (DVM)
• Bench and handheld precision instrumentation
• Process-control and sensor measurement front ends
• Weighing scales and force/pressure measurement
• Temperature and resistance measurement systems
• Legacy/retrofit designs requiring ICL7135-class converters

Why Source XD7135 from Pacific Component Xchange

The XD7135 is a specialty Xinluda converter with little to no authorized-distributor stock, which makes it difficult to source through mainstream channels. Pacific Component Xchange is an independent distributor focused on hard-to-find and obsolete power-management ICs, data converters, and optocouplers. We help engineers and buyers secure low-availability parts like the XD7135 with authenticity verification, careful inspection, and global shipping.

Because the XD7135 is offered as a Request-For-Quote (RFQ) item, pricing and lead time are confirmed per order based on quantity and current supply. Submit an RFQ to Pacific Component Xchange today for the XD7135 and our sourcing team will respond with availability, pricing, and delivery options for your build.
