DN8500A –运算放大器

原厂料号：DN8500A品牌：THERMOPTICS

The DN8500A is an ultra low input bias current

operational amplifier. This amplifier will replace the

discontinued Intersil ICH8500A in most applications. It is

ideally suited for analogelectrometer applications

where high input resistancelow input current are of

prime importance.

This amplifier is unconditionally stablethe input offset

voltage can be adjusted to zero with a 5k! potentiometer.

The input current of the DN8500A is 10 fA maxium over

a temperature range of -25° C to +85° C.

Pin 8 is connected to the case. This permits the designer

to operate the case at any desired potential. This is the

key to achieving the ultra low input current associated

with this amplifier. Forcing the case to the same potential

as the input eliminates current flow between the case and

any of the other Pins.
