ISL70444SEH, ISL73444SEH
19MHz Radiation Hardened 40V Quad Rail-to-Rail Input - Output,
Low-Power Operational Amplifiers
The
ISL70444SEH
and
ISL73444SEH
(ISL7x444SEH) feature
four low-power amplifiers optimized to provide maximum
dynamic range. These operational amplifiers (op amps)
feature a unique combination of rail-to-rail operation on the
input and output as well as a slew enhanced front-end that
provides ultra fast slew rates positively proportional to a given
step size, thereby increasing accuracy under transient
conditions, whether it’s periodic or momentary. The
ISL7x444SEH also offer low power, low offset voltage, and low
temperature drift, making them ideal for applications
requiring both high DC accuracy and AC performance. With
<5µs recovery for Single Event Transients (SET)
(LET
TH
= 86.4MeV•cm
2
/mg), the number of filtering
components needed is drastically reduced. The ISL7x444SEH
are also immune to single event latch-up because they are
fabricated using the Renesas proprietary PR40 Silicon On
Insulator (SOI) process.
The amplifiers are designed to operate over a single supply
range of 2.7V to 40V or a split supply voltage range of ±1.35V to
±20V. Applications for these amplifiers include precision
instrumentation, data acquisition, precision power supply
controls, and process controls.
The ISL7x444SEH are available in a 14 Ld hermetic ceramic
flatpack and die forms that operate across the temperature
range of -55°C to +125°C.

NOTES:
1. These Pb-free Hermetic packaged products employ 100% Au plate - e4 termination finish, which is RoHS compliant and compatible with both SnPb
and Pb-free soldering operations.
2. Specifications for Rad Hard QML devices are controlled by the Defense Logistics Agency Land and Maritime (DLA). The SMD numbers listed must be
used when ordering.
3. The /PROTO and /SAMPLE are not rated or certified for Total Ionizing Dose (TID) or Single Event Effect (SEE) immunity. These parts are intended for
engineering evaluation purposes only. The /PROTO parts meet the electrical limits and conditions across the temperature range specified in the DLA
SMD and are in the same form and fit as the qualified device. The /SAMPLE die is capable of meeting the electrical limits and conditions specified
in the DLA SMD at +25°C only. The /SAMPLE is a die and does not receive 100% screening across the temperature range to the DLA SMD electrical
limits. These part types do not come with a certificate of conformance because there is no radiation assurance testing and they are not DLA qualified
devices.
4. The evaluation board uses /PROTO parts. The /PROTO parts are not rated or certified for Total Ionizing Dose (TID) or Single Event Effect (SEE)
immunity.
