The ICL7605CJN is a monolithic CMOS chopper-stabilized operational amplifier manufactured by Intersil (now Renesas). It offers extremely low input offset voltage and drift, making it suitable for precision instrumentation and measurement applications. Its chopper stabilization technique continuously corrects for offset errors, resulting in high accuracy and stability over temperature and time.

Applications:

• Precision instrumentation amplifiers
• Thermocouple amplifiers
• Strain gauge amplifiers
• pH meters
• High-resolution data acquisition systems

Additional Details:

The ICL7605CJN is available in a 14-pin PDIP (Plastic Dual In-line Package). The operating temperature range is typically 0°C to +70°C. The chopper frequency is internally set, eliminating the need for external components. This amplifier is designed to provide superior performance compared to traditional bipolar operational amplifiers in applications requiring high precision and stability. The common-mode rejection ratio (CMRR) is typically 110dB, and the power supply rejection ratio (PSRR) is typically 100dB.
