Chipanalog CA-IS3050WG
The CA-IS305x family of devices is galvanically-isolated controller area network (CAN) transceiver that has superior isolation and CAN performance to meet the needs of the industrial applications. All devices of this family have the logic input and output buffers separated by a silicon oxide (SiO2) insulation barrier that provides galvanic isolation. Isolation improves communication by breaking ground loops and reduces noise where there are large differences in ground potential between ports. Both the CA-IS3050 and the CA-IS3052 are available in wide-body SOIC8 and SOIC16 packages, but offer different pinout; also, the CA-IS3050 is available in DUB8 and super wide-body SOIC8 packages. The SOIC16-WB (W) is the industry standard isolated CAN package while the SOIC8-WB (G) and DUB8 (U) are much smaller packages that further reduce the board space in addition to reduced components due to integration of isolation and CAN with protection features. The CA-IS3050U provides up to 3.75VRMS (60s) of galvanic isolation; The CA[1]IS305xG/W provide up to 5kVRMS (60s) of galvanic isolation; The CA-IS3050WG provides up to 7.5kVRMS (60s) of galvanic isolation.
