Chopper-Stabilized Op Amps  
General Description  
Features  
Maxim’s ICL7650/ICL7653 are chopper-stabilized  
amplifiers, ideal for low-level signal processing applica-  
tions. 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 operat-  
ing temperature range.  
ICL7650/53 are Improved Second Sources to  
ICL7650B/53B  
Lower Supply Current: 2mA  
Low Offset Voltage: 1µV  
No Offset Voltage Trimming Needed  
High-Gain CMRR and PSRR: 120dB min  
Lower Offset Drift with Time and Temperature  
Extended Common-Mode Voltage Range  
Low DC Input Bias Current: 10pA  
Monolithic, Low-Power CMOS Design  
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.  
Ordering Information  
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 over-  
load recovery time.
