Analog Devices has introduced a dual, precision operational amplifier with more than ±30V of integrated input over-voltage protection (OVP).

This extends 32V above and below the supply rails, and according to the supplier can eliminate or minimise the need for external protection circuits. 

Since op amps can be damaged if the signal they are monitoring is live when its power supplies are not available, the ADA4096-2’s input OVP was designed to remain active even when power is not applied.

“This protects the inputs even during power on/power off sequencing and in low power sleep and standby modes of operation and helps ensure continuous operation of the entire electronic system,” said the supplier.

The ADA4096-2 draws 60µA per amplifier.

The amp has 800kHz of unity gain bandwidth. It has typical offset voltage of 35µV and 1µV/°C typical of temperature drift.

Low voltage noise is 27nV/rootHz. 

The ADA4096-2 is fully specified to operate from a 3-V to 30-V single-voltage supply over the extended industrial temperature range (−40°C to +125°C).
