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.
