High Temperature General Purpose Operational Amplifier from CISSOID

CHT-OPA fits market requirements for Oil&Gas, Aeronautics, Space and Automotive applications with large temperature range from -55°C to 225°C. It can operate with both single and symmetrical power supply from 4.5V to 20V. The gain of the amplifier ranges from 100dB at -55°C to 80dB at high temperature with a Gain Bandwith Product of 1.8MHz and a typical offset of 2.5mV. The output current capability is up to 15mA.

Beyond the standard operating conditions, the CHT-OPA has been tested with success from -200°C to +300°C (with derated merit factors), which gives it an absolute record operating range of 500°C. Therefore, the amplifier can be used in applications as diverse as geothermy with extremely High Temperature, and planetary missions with cryogenic conditions.

This new general purpose amplifier is part of Cissoid’s ‘product roadmap’, offering customers a more and more complete portfolio of Extreme Temperature Electronics components. CHT-OPA is an essential building block for complete High Temperature systems. Together with Cissoid’s Analog-to-Digital converter (ADC), voltage regulators and voltage references, oscillators and timers, customers can design virtually any function for Extreme Temperature. Functionality beyond the standard temperature range of -55°C to 225°C also shows the robustness of Cissoid’s complete development process, from silicon design to every detail of the assembly and test.
