• WIDE POWER-SUPPLY RANGE:

The OPA454 is a low-cost operational amplifier with

±5V (10V) to ±50V (100V)

high voltage (100V) and relatively high current drive

(25mA).

It

is

unity-gain

stable

and

has

a

gain-bandwidth product of 2.5MHz.

• WIDE OUTPUT VOLTAGE SWING: 1V to Rails

standard

low-voltage logic circuitry. This high-voltage op amp

provides excellent accuracy, wide output swing, and
