  1. OPAL: Ultra High Precision Dual Op-Amp

    OPAL: Ultra High Precision Dual Op-Amp

    CHT-OPAL is an ultra high-precision, dual operational amplifier designed for applications that require very low offset and very low noise.  

    Both amplifiers can be configured as a differential amplifier or as an instrumentation amplifier (combined with a third, external amplifier cell and with external resistors).

    Features

        • Junction operating temperature from -55°C to +225°C
        • Product gain bandwidth: 2.8 MHz typ
        • Stable for gains above 3 (with <50pF load) and 5 (with 50~200pF load)
        • Automatic offset compensation
        • Validated at 225°C for 1000 hours

  2. RUBY: Triple Op-Amp with Voltage Regulator

    RUBY: Triple Op-Amp with Voltage Regulator

    The CHT-RUBY is a general-purpose triple operational amplifier combined with a Band Gap voltage reference for applications over the temperature range from -55 to +225°C. 

    The three operational amplifiers can be configured in an instrumentation amplifier with external resistors, while the built-in voltage reference provides complete bridge excitation for sensor applications.

    The total precision (absolute plus temperature drift) of the voltage reference is better than 2%. It exhibits a quiescent current consumption of 700μA, and an output current capability of up to 25mA into an external load at 225°C.

    The operational amplifiers can operate with either single or symmetrical power supplies.

    Features

        • Functional from -55 to +225°C (Tj)
        • +4.5 to +20V supply voltages
        • Validated at 225°C for 1000 Hours
        • Available in ceramic SOIC16 package
        • Fixed regulated +5V
        • 700μA stand-by current
