Description

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.

The ICL7650B/ICL7653B are exact replacements for Intersil's ICL7650B/ICL7653B. These devices have a 10µV max offset voltage, a 0.1µV/°C max input offset voltage temperature coefficient, and a 20pA max bias current—all specified over the commercial temperature range.
