Munich, Germany - Featuring a very small form factor SMT (surface-mount technology) package, the ADM3251E transceiver integrates a line driver, line receiver, oscillator, rectifier, regulator, voltage doubler, voltage inverter and transformers into a single-chip solution that isolates both the data and power lines on chip. The transceiver's SMT package (Pb-free 13mm-10.56mm 20-lead WSOIC) allows system manufacturers to mount the device using fully automated production tools, which reduces manufacturing steps and improves mechanical performance. The smaller footprint additionally frees up circuit board space for other system functions. The highly integrated device provides a robust serial communications interface with isolated power for use in harsh HVAC, industrial and medical applications.
RS-232 transceiver for use in industrial environments
The transceiver incorporates iCoupler and isoPower isolation technologies and is the first surface mount RS-232 transceiver to feature full isolation of both the data lines and power. With a 2.5kV isolation rating, the RS-232 transceiver complies with industry-standard isolation regulations, including UL1577 and DIN VDE 0884-10, ensuring it will meet the robustness levels required in noisy operating environments such as isolated RS-232 diagnostic data ports in HVAC building control systems, industrial automation and control applications, point-of-sale equipment, programmable logic controllers, telecom and medical equipment. The SMT package reduces board space by 45 percent compared with traditional ICs and helps to accelerate the manufacturing process and lower system development costs.
