Data Acquisition

Data acquisition covers the parts that move signals between the analog world and a processor. On this page you will mostly find analog-to-digital converters, digital-to-analog converters, analog front ends, multiplexers, sample-and-hold amplifiers, and the occasional complete data acquisition module. These show up everywhere: PLC input cards, battery test equipment, medical monitors, vibration sensors, weigh scales, and lab instruments all lean on some flavor of ADC or DAC, and the part that works fine in a consumer gadget often will not survive an industrial temperature spec. When engineers and buyers come to us for these parts, they usually start with resolution and sample rate, but the conversation quickly moves to interface type, reference requirements, and package. A 16-bit ADC in a tiny QFN is a different sourcing problem than the same die in a TSSOP, and plenty of designs still run on older through-hole parts that the franchised channel stopped stocking years ago. That is where lead time becomes the real trade-off. A common scenario: the franchised distributor quotes 26 weeks on an ADI or TI converter, while the open market has reels sitting in a warehouse somewhere. The catch is you need to trust the source, because data acquisition ICs are among the most counterfeited parts we see, especially high-resolution ADCs and anything from Analog Devices with a long backorder history. Date codes, original packaging, and traceable lot information matter more here than shaving a few cents off the unit price. Buyers also ask about cut tape versus full reels, since many of these parts go into low-volume, high-mix production. If you are sourcing converters or front ends, check current stock and send us your bill of materials at icxing.com and we will get back to you with pricing and availability.
