3 Description

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

purpose operational amplifiers for space application.

The device offers exceptional DC precision and AC

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

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

typical), low noise (10.8nV/√Hz and 1.8μVPP), and

4.5MHz bandwidth.

Unique features such as differential and commonmode

input-voltage range to the supply rail, high

output current (±75mA), high slew rate (21V/μs), and

high capacitive load drive (1nF) make the OPA4H199-

SP a robust, high-performance operational amplifier

for high-voltage space applications.

The OPA4H199-SP 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-SP is

specified from –55°C to 125°C.
