The ICL7652CTV is a precision CMOS chopper-stabilized operational amplifier from Intersil (now Renesas). This amplifier is designed for applications requiring extremely low offset voltage and drift, such as precision instrumentation, data acquisition, and sensor signal conditioning. The chopper stabilization technique continuously corrects for offset errors, resulting in exceptional accuracy and stability over temperature and time.

Applications:

• Precision instrumentation amplifiers
• Thermocouple amplifiers
• Strain gauge amplifiers
• Precision voltage references
• High-resolution data acquisition systems
• Medical instrumentation

Features:

• Ultra-Low Input Offset Voltage (0.5µV max)
• Low Input Offset Voltage Drift (0.005µV/°C typ)
• High Open-Loop Gain (140dB typ)
• Low Input Bias Current (10pA typ)
• Wide Supply Voltage Range (±4.5V to ±16V)
• Low Noise
• Internal Chopping Frequency

Benefits:

• Extremely accurate measurements due to ultra-low offset voltage and drift.
• Reduced calibration requirements in precision instrumentation.
• High sensitivity in low-level signal amplification.
• Improved long-term stability of measurement systems.
• Versatile operation with a wide supply voltage range.
• Minimized noise interference in sensitive applications.

Additional Details:

The ICL7652CTV is available in a 14-pin PDIP (Plastic Dual In-line Package). The operating temperature range is typically 0°C to +70°C. The internal chopper frequency eliminates the need for external clocking components. This amplifier provides superior performance compared to traditional bipolar operational amplifiers where high precision and stability are critical. The common-mode rejection ratio (CMRR) is typically 120dB, and the power supply rejection ratio (PSRR) is typically 120dB.
