The ICL7650SCPDZ is a 2MHz Super Chopper-stabilized Operational Amplifier offers exceptionally low input offset voltage and is extremely stable with respect to time and temperature. It is a direct replacement for the industry-standard ICL7650 offering improved input offset voltage, lower input offset voltage temperature coefficient, reduced input bias current and wider common mode voltage range. All improvements are highlighted in bold italics in the Electrical Characteristics section. Critical parameters are guaranteed over the entire commercial temperature range. Intersil"s unique CMOS chopper-stabilized amplifier circuitry is user-transparent, virtually eliminating the traditional chopper amplifier problems of intermodulation effects, chopping spikes and over range lockup.
General Description Maxim’s ICL7650/ICL7653 are chopper-stabilized amplifiers, ideal for low-level signal processing applications. Featuring high performance and versatility, these devices combine low input offset voltage, low input bias current, wide bandwidth, and exceptionally low drift over time and temperature. Low offset is achieved through a nulling scheme that provides continuous error correction. A nulling amplifier alternately nulls itself and the main amplifier. The result is an input offset voltage that is held to a minimum over the entire operating temperature range.
