Product Details

The AD203SN is designed and built expressly for use in hostile operating environments. The AD203SN is also an integral member of Analog Devices' AD200 Series of low cost, high performance, transformer coupled isolation amplifiers. Technological innovations in circuit design, transformer construction, surface mount components and assembly automation have resulted in a rugged, economical, military temperature range isolator that either retains or improves upon the key performance specifications of the AD202/AD204 line.

The AD203SN provides total galvanic isolation between the input and output stages of the isolation amplifier, including the power supplies, through the use of internal transformer coupling. The functionally complete design of the AD203SN, powered by a single + 15 V de supply, eliminates the need for an external de/de converter. This permits the designer to minimize the necessary circuit overhead and consequently reduce the overall design and component costs. Furthermore, the power consumption, nonlinearity and drift characteristics of transformer coupled devices are vastly superior to those achievable with other isolation technologies, without sacrificing bandwidth or noise performance. Finally, the AD203SN will maintain its high operating performance even under sustained common mode stress.

The design of the AD203SN emphasizes maximum flexibility and ease of use in a broad range of applications where signals must be measured or transmitted under high CMV conditions. The AD203SN has a ± 10 V output range, an uncommitted input amplifier, an output buffer, a 10 kHz full power bandwidth and a front-end isolated power supply of ± 15 V dc @ ± 5 mA.
