• Input Offset Voltage: 0.7µV (typical)
• Input Bias Current: 10pA (typical)
• Input Offset Current: 5pA (typical)
• Gain Bandwidth Product: 2MHz (typical)
• Slew Rate: 1.6V/µs (typical)
• Common-Mode Rejection Ratio (CMRR): 120dB (typical)
• Power Supply Rejection Ratio (PSRR): 120dB (typical)
• Operating Temperature Range: 0°C to +70°C (commercial grade)
• Package: 8-Pin PDIP (Plastic Dual In-Line Package)

Description:

The ICL7650CPA is a chopper-stabilized operational amplifier designed for applications requiring ultra-low offset voltage, low drift, and high precision. It uses auto-zeroing technology to minimize offset voltage and drift over time and temperature.

Features:

• Ultra-Low Offset Voltage: 0.7µV (typical)
• Low Drift: 0.01µV/°C (typical)
• Low Input Bias Current: 10pA (typical)
• High CMRR & PSRR: 120dB (typical)
• Wide Supply Range: ±1.5V to ±8V
• Chopper-Stabilized Design: Eliminates 1/f noise and drift
• No External Capacitors Required for auto-zeroing

This amplifier is commonly used in precision instrumentation, medical equipment, strain gauge amplifiers, and low-level signal conditioning applications.

(Note: The ICL7650CPA is an older part, and availability may vary as INTERSIL was acquired by Renesas.)
