OPA445

SBOS156B − MARCH 1987 − REVISED APRIL 2008

High Voltage FET-Input

OPERATIONAL AMPLIFIER

F_DEATURES

DESCRIPTION

WIDE-POWER SUPPLY RANGE:

10V to 45V

The OPA445 is a monolithic operational amplifier capable

of operation from power supplies up to 45V and output

currents of 15mA. It is useful in a wide variety of

applications requiring high output voltage or large

common-mode voltage swings.

HIGH SLEW RATE: 15V/µs

LOW INPUT BIAS CURRENT: 10pA

STANDARD-PINOUT TO-99, DIP, SO-8

PowerPAD, AND SO-8 SURFACE-MOUNT

PACKAGES

The OPA445’s high slew rate provides wide power-

bandwidth response, which is often required for

high-voltage applications. FET input circuitry allows the

use of high-impedance feedback networks, thus minimiz-

ing their output loading effects. Laser trimming of the input

circuitry yields low input offset voltage and drift.

AUDIO

The OPA445 is available in standard pinout TO-99, DIP-8,

and SO-8 surface-mount packages as well as an SO-8

PowerPAD package for reducing junction temperature. It

is fully specified from −25°C to +85°C and operates from

−55°C to +125°C. A SPICE macromodel is available for

design analysis (from www.ti.com).
