CISSOID, a specialist in high-temperature semiconductor solutions, has introduced OPAL, a high precision operational amplifier that is guaranteed for operation from -55°C up to +225°C. OPAL is a dual Op Amp specifically designed to meet very tough environmental constraints on sensors used in automotive, industrial and general High Reliability applications such as aeronautics, military and down-hole tools (Oil & Gas) electronics.
Among the device’s key features are: low input offset (50µV typ.), low noise (5 µVpp typ.) and single +5V ±10% power supply.
A first product flavour which is now available is the CHT-OPAL which is 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 flavour will be available in the next few weeks, the CMT-OPAL, which will have a maximum temperature of +175°C. Packaged in a Plastic SOIC16, it brings a cost-optimised solution for 175°C max requirements, while taking full advantage of CISSOID’ best-in-class lifetime en reliability features. A TSSOP16 flavour will also be available upon request for applications where component size must be minimized.
Commenting Jean-Christophe Doucet, VP of Marketing at CISSOID said: “We are seeing an increasing demand for reliable, high-temperature signal conditioning solutions, in a number of sensing applications in automotive and industrial markets among others. Our goal is to simplify the sensor architectures, in particular using simpler – and lower cost – cables and harnessing while keeping the complex signal processing remote (i.e. outside the “hot” zone where the sensor is). With OPAL, CISSOID brings a solution of choice: placing the upfront signal amplification block within the sensor itself. None of the existing integrated solutions were satisfactory so far, as the performance and lifetime were too limited. CISSOID now brings the performance up and the cost down, opening a wide new field of possibilities to its customers”.
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.
