Converter Transformers hasten transceiver implementation.

Press Release Summary:

Offering carefully controlled turns ratios to ensure consistent performance, 782482 series offers compatibility with Analog Devices' ADM2482/7 transceiver chipsets to accelerate implementation of isolated RS-485 and RS-422 interfaces. Toroidal construction helps minimize EMI, and dual-in-line package, which measures 0.385 x 0.360 x 0.25 in., uses UL94 V-0 materials. Available with 3.3 and 5.0 V nominal input voltages, series offers 3.3 V nominal output and 4.0 kVDC isolation.

Original Press Release:

Low EMI Converter Transformers Approved for Use with Analog Devices' High Speed Transceivers

Compatibility with ADM2482 /7 chipsets speeds implementation of isolated RS-485 and RS-422 interfaces
Low profile device offers 4kVDC isolation
Choice of 3.3V and 5.0V input voltages
Toroidal construction maximizes efficiency and reduces EMI

Murata Power Solutions has introduced a new series of converter transformers specifically designed for use with Analog Devices' ADM2482/7 transceiver chipsets used to provide isolated RS-485 and RS-422 interfaces. The 782482 series has carefully controlled turns ratios to ensure consistent performance while a toroidal construction helps minimize electromagnetic interference (EMI).

Housed in an industry-standard, dual-in-line (DIL) package using UL94 V-0 materials, the low-profile 782482 series has overall dimensions of 0.385in. (9.77mm) x 0.360in. (9.14mm) x 0.25in. (6.35mm) high. Nominal input voltages are 3.3V for the 782482/33VC and 5.0V for the 782482/53VC; both models have a nominal output voltage of 3.3V and provide 4.0kVDC isolation.

An industrial temperature range of -40°C to +85°C makes the 782482 series suitable for use in a wide range of applications. Both models are RoHS compliant and backward compatible with Sn/Pb soldering systems. Surface mount versions of the new converter transformers are under development.

Analog Devices' ADM2482/7 are isolated data transceivers with ±15 kV ESD protection and are suitable for high speed, half-duplex or full-duplex communication on multipoint transmission lines. The devices employ the Analog Devices iCoupler® technology to combine a three-channel isolator, a three-state differential line driver, and a differential input receiver into a single package.
