Import Adg731bsuz — Buy in wholesale FOB from Supplier in China

The ADG731BSUZ is a 32-to-1 analog multiplexer IC from AMS ELEctronics Company, housed in a 48-pin TQFP package for surface-mount assembly. It routes one of 32 input channels to a single output under digital control, making it suitable for complex signal management in data acquisition and communication systems. The device operates from a single supply and is fabricated on a CMOS process for low quiescent current. Its 5 ohm typical on-resistance helps preserve signal integrity across the audio and low-frequency range. The TQFP-48 footprint measures 7mm by 7mm with 0.5mm pitch, a standard size for mid-density PCBs. The part number follows Analog Devices' legacy naming, though AMS ELEctronics Company sources and supplies it to global manufacturing buyers.

The die is built on a silicon CMOS process with metal-gate technology that yields low charge injection and minimal crosstalk between channels. The 32:1 architecture uses a binary decoder to select channels, with break-before-make switching to prevent momentary shorting of inputs. Typical off-isolation exceeds 60dB at 1MHz, while the -3dB bandwidth extends to 200MHz, supporting video and fast data signals. The device handles rail-to-rail analog signals when powered from 1.8V to 5.5V. Power consumption scales with supply voltage, drawing microamperes in static state. The TQFP package employs copper leadframes with matte tin plating, standard for RoHS-compliant semiconductor assembly. Thermal resistance from junction to ambient is typical of thin quad flat packs, so board layout with adequate ground plane area matters for reliability.

Target buyers include OEMs building test equipment, medical monitors, industrial process controllers, and telecom infrastructure where multiple sensor or line inputs must share a single ADC or DSP channel. The ADG731BSUZ suits designs needing more inputs than the common 8:1 or 16:1 alternatives without adding cascaded parts. Engineers should confirm with AMS ELEctronics Company whether stock is factory-new, the date code range, and whether programming or configuration support is available. The supplier lists FOB and CIF as possible shipping arrangements, though exact Incoterms and minimum order quantities require direct negotiation. Buyers sourcing from China should verify customs HS classification, which for this multiplexer typically falls under semiconductor IC categories.

AMS ELEctronics Company operates from Room 3028, Shangdi Mansion, 30 Xinxi Road, Beijing 100085, China, placing it in the Haidian district near China's semiconductor design and IT corridor. The supplier holds a Harbor trust tier on the platform, which indicates a baseline verification level rather than premium accreditation. The response rate shows 0.00 percent with zero average response hours recorded, meaning prospective buyers should treat direct outreach as essential and not rely on rapid quotation turnaround. No manufacturing certifications, ISO registrations, or capacity claims appear in the available profile, so buyers must request these directly.

The company lists the ADG731BSUZ among its stock, positioning itself as a trading or distribution channel for Analog Devices-branded or compatible multiplexers rather than an original manufacturer. Its address suggests office-based operations rather than factory premises, consistent with component trading common in Beijing's electronics markets. Buyers should verify whether AMS ELEctronics Company holds authorized distributor status or sources through the gray market, as this affects warranty, traceability, and counterfeit risk. The listing mentions flexible MOQ and competitive pricing, but exact figures are absent from the profile and must be negotiated case by case.
