3 Description

The

OPAx990

family

(OPA990,

OPA2990,

and

OPA4990) is a family of high voltage (40-V) general

purpose operational amplifiers. These devices offer

excellent

DC

precision

and

AC

performance,

including rail-to-rail input/output, low offset (±300 µV,

typ), and low offset drift (±0.6 µV/°C, typ).

Unique features such as differential and common-

mode input voltage range to the supply rail, high

short-circuit current (±80 mA), high slew rate (4.5

V/µs),

and

shutdown

make

the

OPAx990

an

extremely flexible, robust, and high-performance op

amp for high-voltage industrial applications.

The OPAx990 family of op amps is available in micro-

size packages (such as X2QFN, WSON, and SOT-

553), as well as standard packages (such as SOT-23,

SOIC, and TSSOP), and is specified from –40°C to

125°C.
