General Description

BU7485G/BU7486xxx/BU7487xx are CMOS operational

amplifiers with input ground sense and full swing output.

This

series

has

extended

operational

amplifiers

BU7485SG/BU7486Sxxx/BU7487Sxx which can operate

over a wider temperature range (-40°C to +105°C).

These ICs have wide band, high slew rate, low voltage

operation and low input bias current, making the

operational amplifiers suitable for portable equipment

and sensor application.

Features

 High Slew Rate
