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.
