Analog DevicesADUM3195BRQZSpecial Purpose Amplifiers

Unlike optocoupler-based solutions, which have an uncertain current transfer ratio over their lifetime and at high temperatures, the ADuM3195 transfer functions do not change over their 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 reference outputs.

The ADuM3195 is packaged in a 16-lead quarter small outline package (QSOP) for a 3000 V_rms isolation voltage rating.
