High-stability Isolated Error Amplifier
ADuM4190
Preliminary Technical Data
FEATURES
GENERAL DESCRIPTION
Stable Over Time and Temperature
0.5% initial accuracy
1% accuracy over the full temp range
For Type II or Type III compensation networks
Reference voltage 1.225V
Compatible with DOSA
Low power operation: <7 mA total
Wide Supply Voltage Range
The ADuM4190 is an isolated error amplifier based on Analog
Devices, Inc. iCoupler® technology. The ADuM4190 is ideal for
linear feedback power supplies with primary side controllers
enabling improvements in transient response, power density
and stability as compared to commonly used optocoupler and
shunt regulator solutions.
Unlike optocoupler-based solutions, which have an uncertain
current-transfer-ratio over lifetime and at high temperatures,
the ADuM4190 transfer function does not change over lifetime
and is stable over a wide temperature range of -40C to 125C.

DD1 – 3V to 20V
DD2 - 3V to 20V
Bandwidth – 400kHz
Isolation Voltage
Included is a wide band operational amplifier which can be used
to set up a variety of commonly used power supply loop
compensation techniques. The ADuM4190 is fast enough to
allow a feedback loop to react to fast transient conditions and
over current conditions. Also, included is a high accuracy
1.225V reference to compare with the supply output set point.
5.0kVrms reinforced
Wide temperature range:
-40C to 125°C ambient operation
150C maximum junction temperature
APPLICATIONS
Linear Power Supplies
Inverters
The ADuM4190 is packaged in a wide body SO-16 package for
reinforced 5kVrms isolation rating.
