Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.


Description

Maxim's ICL7650/ICL7653 are chopper-stabilized amplifiers, ideal for low-level signal processing applica ions. Featuring high performance and versatility, these devices combine low input offset voltage, low input bias current, wide bandwidth, and exceptionally low drif over time and temperature. Low offset is achieved hrough a nulling scheme that provides continuous error correction. A nulling amplifier alternately nulls tself and the main amplifier. The result is an input offse voltage that is held to a minimum over the entire operat ng temperature range.


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


A 14-pin version is available that can be used with either an internal or external clock. The 14-pin version has an output voltage clamp circuit to minimize overload recovery time.
