Chipanalog

Chipanalog is a Shanghai-based isolation specialist, and the three profiles here all sit in the same working slot: half-duplex RS-485 links that must cross a galvanic barrier in industrial controls, meters, drives and building systems. Two codes, the CA-IS3082WX and the CA-IS3092W, come in wide-body SOIC-16 packages. The third, the CA-IS2082B profiled from Chipanalog's current English datasheet, is the compact SSOP-16 option rated at 3.0 kVrms isolation with data rates up to 20 Mbps, a 1/8-unit load for up to 256 nodes and -40 to +125 °C operation. Isolation voltage, transient immunity, supply range and data rate are per-code figures here, not shared constants, so qualify against the datasheet of the exact code on your BOM. Several Chipanalog codes differ by one suffix letter that changes the package or rating, so state the complete code in your RFQ.

Sourcing notes for Chipanalog parts. Always quote the complete manufacturer ordering code — package, temperature grade, speed or accuracy grade, and packing (reel, tube or tray) all change availability and price, and suffixes are where most mismatches happen. Check the lifecycle status on the manufacturer site before committing to a multi-year build; parts flagged not-recommended or obsolete need a last-time-buy plan or a verified alternate lined up early. With every offer, request traceability documents — date code, lot code and original packing — and confirm the inspection steps your supplier applies to high-risk lots.
