GENERAL DESCRIPTION

The ADuM31951 are isolation amplifiers based on Analog Devices,

Inc., iCoupler? technology. The ADuM3195 have very low offset

and gain error, making them ideal for many isolated voltage sensing

applications.

Unlike optocoupler-based solutions, which have an uncertain current

transfer ratio over lifetime and at high temperatures, the ADuM3195

transfer functions do not change over lifetime, and are

stable over a wide temperature range of ?40°C to +125°C.

Included in the ADuM3195 are wideband operational amplifiers

useful for a variety of commonly used applications. Included in the

ADuM3195 are two high accuracy 2.5 V references outputs.

The ADuM3195 is packaged in a 16-lead quarter small outline

package (QSOP) for a 3000 V rms isolation voltage rating.
