19MHz Radiation Hardened 40V Dual Rail-to-Rail Input-Output, Low-Power

Operational Amplifier

The ISL70244SEH and ISL73244SEH (ISL7x244SEH) feature

Features

two low-power amplifiers optimized to provide maximum

• Electrically screened to DLA SMD # 5962-13248

dynamic range. These operational amplifiers (op amps)

feature a unique combination of rail-to-rail operation on the

input and output and a slew enhanced front end that provides

ultra fast slew rates positively proportional to a given step size.

These features increase accuracy under both periodic and

transient conditions. The ISL7x244SEH also offers low power,

low offset voltage, and low temperature drift, which makes it

ideal for applications requiring both high DC accuracy and AC

performance. With <5µs recovery for Single Event Transients

(SET) (LET_TH= 86.4MeV•cm²/mg), the number of filtering

components needed is drastically reduced. The ISL7x244SEH

is also immune to single-event latch-up because it is fabricated

in the Renesas proprietary PR40 Silicon On Insulator (SOI)

process.

±20V. Applications for these amplifiers include precision

instrumentation, data acquisition, precision power supply

controls, and process controls.

The ISL7x244SEH is available in a 10 Ld hermetic ceramic

flatpack that operates across the temperature range of -55°C

to +125°C.
