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.
