3 Description

The OPA4H199-SEP is a high voltage (40 V) general

purpose operational amplifiers for space application.

The device offers exceptional DC precision and AC

performance, including rail-to-rail input/output, low

offset (±125 μV, typ), low offset drift (±0.3 μV/°C, typ),

low noise (10.8 nV/√Hz and 1.8 μVPP), and 4.5-MHz

bandwidth.

Unique features such as differential and commonmode

input-voltage range to the supply rail,

high output current (±75 mA), high slew rate

(21 V/μs), and high capacitive load drive (1

nF) make the OPA4H199-SEP a robust, highperformance

operational amplifier for high-voltage

space applications.

The OPA4H199-SEP is available in a small-sized,

radiation-hardened plastic, 14-pin SOT-23 (DYY)

package. The SOT-23 (DYY) package has a body

size that is less than 1/5th of the size of traditional

14-pin ceramic packages. The OPA4H199-SEP is

specified from –55°C to 125°C.
