High-Precision Dual Op Amp for High Temperature Applications

CISSOID introduces OPAL, the only high precision operational amplifier guaranteed for operation from -55°C up to +225°C. OPAL is a dual Op Amp specifically designed to meet the toughest environmental constraints of sensors in automotive, industrial and general High Reliability applications such as aeronautics, military and down-hole tools (oil and gas) electronics. Key features include low input offset (50µV typ.), low noise (5 µVpp typ.) and single +5V ±10% power supply.

A first product flavor now available is CHT-OPAL, guaranteed for operation from -55°C up to +225°C. It is available in a thin dual flat pack (TDFP) surface mount, hermetically sealed ceramic package, with footprint of only 5 x 5.5mm. A second product flavor will be available in the coming weeks, the CMT-OPAL, with a maximum temperature of +175°C. Packaged in a Plastic SOIC16, it brings a cost-optimized solution for 175°C max requirements, while taking full advantage of CISSOID' best-in-class lifetime en reliability features. A TSSOP16 flavor will also be available upon request for applications where component size must be minimized.

Typical applications include gas sensors (e.g. EGR valves in automotive), boilers, flame detectors, temperature, pressure and  position sensors, strain gage amplifiers, photodiode and PMT amplifiers, but also transmitters (e.g. 4-20mA...)

A product datasheet is available now from CISSOID's website (OPAL datasheet). CHT-OPAL can be ordered for sampling and evaluation under the part number CHT-GEM6489A -TDFP16-T. CMT-OPAL will be available under the part number CMT-GEM6489A-PSOIC16-T. Under request, tiny TSSOP can also be provided for miniaturization.
