Chicago, Ill. Newark, part of Premier Farnell, is the exclusive distributor of Linear Technology’s Isolator μModule Transceiver evaluation kits. The kits are available for same-day shipping at http://www.newark.com/linear-technology.
The DC1503A evaluation kit supports Linear Technology’s LTM2881 and the DC1554A supports the LTM2882. Both boards are available in either 3.3 V or 5 V.
The LTM2881 is a complete 2500 VRMS galvanically isolated, full duplex RS485/RS422 μModule transceiver with integrated 1-W isolated power that requires no external components. Up to 62 percent efficiency is achievable, with surplus power available at a 5-V regulated output. Additional features include integrated pin-selectable 120-ohm termination, along with a dedicated logic supply pin and spare isolated logic channel.
The LTM2882 is a 2500 VRMS galvanically isolated dual RS232 μModule transceiver with integrated 1-W isolated power. It also requires no external components. Up to 65 percent efficiency is achievable, with surplus power available at a 5-V regulated output. The device meets RF and magnetic field immunity test requirements per European standard EN550024.
The isolator μModule technology is well suited for breaking ground loops, and for systems with large ground-to-ground differentials and common mode transients. Common mode rejection of up to 30 kV/μs is achievable, while continuing to communicate through the event.
Newark stocks all temperatures, voltages and packages of the device.
A Linear Technology engineer is available to answer product questions and provide technical support for these products at element14. This is in addition to the technical support Newark offers 24 hours a day, Monday-Friday at www.newark.com.
