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.
