High Stability, Isolated Error Amplifier Enhanced Product ADuM4190-EP FEATURES GENERAL DESCRIPTION Stable over time and temperature
The ADuM4190-EP1 is an isolated error amplifier based on
0.5% initial error accuracy
Analog Devices, Inc., iCoupler® technology. The ADuM4190-EP
1% accuracy error over the full temperature range
is ideal for linear feedback power supplies. The primary side
Compatible with Type II or Type III compensation networks
controllers of the ADuM4190-EP enable improvements in
