ICL7650SCPDZ ,Chopper-Stabilized Operational Amplifier, 2MHz GBP, DIP Package, Low Offset

The ICL7650SCPDZ is a high-performance, super chopper-stabilized operational amplifier, manufactured by Intersil (now part of Renesas Electronics). It is designed for applications that demand extremely low offset voltage, low drift, and high precision over a wide temperature range. This amplifier is a direct replacement for the industry-standard ICL7650, with improved specifications, including a lower input offset voltage, reduced input bias current, and wider common-mode voltage range.

The unique CMOS architecture of the ICL7650S eliminates the traditional chopper amplifier's offset voltage drift and low-frequency noise, making it ideal for precision instrumentation and low-frequency applications.

The amplifier features an offset voltage of ±0.5 µV (typical), a gain bandwidth of 2 MHz, and an ultra-low bias current of only 10 pA, making it suitable for applications like sensor interfacing, data acquisition systems, medical instrumentation, and high-precision measurements.

Key Features :

• Low Input Offset Voltage: 0.5 µV, providing exceptional accuracy for precision applications.
• Wide Gain Bandwidth Product (GBP): 2 MHz, supporting high-frequency operation with stability.
• High CMRR: 150 dB (typical), ensuring high stability across varied input voltages.
• Extremely Low Bias Current: Max 10 pA, which is critical in maintaining input integrity in sensitive applications.
• Temperature-Stable: Operates reliably over a wide temperature range of 0°C to +70°C.
• Enhanced Protection: Features ESD protection and an internal guard to minimize leakage and ensure operational reliability in demanding environments.
