ICL7650SIPA-1

Overview

The ICL7650SIPA-1 is a chopper-stabilized operational amplifier manufactured by Harris Corporation. It features a single circuit with one channel, housed in a 14-pin DIP package. The device operates within a supply voltage range of 4.5V to 16V and consumes 2 mA of current. Key electrical parameters include a bandwidth of 2 MHz, a slew rate of 2.5 V/µs, and a gain-bandwidth product of 2 MHz. It exhibits a common-mode rejection ratio of 120 dB, an input offset voltage of 700 µV, and an input bias current of 4 pA. The component functions reliably across a temperature range of 0°C to 70°C.

Feature Summary

• Chopper-stabilized architecture for high precision
• High impedance differential CMOS inputs
• Low input offset voltage characteristics
• Internally compensated for stable unity gain operation

Applications

• Laser average optical power control systems
• Precision DC signal amplification
• Fiber optic communication equipment
• High impedance sensor interfaces

Procurement Notes

Verify the manufacturer designation as Harris Corporation against the specific datasheet revision. Confirm the suffix 'I' indicates industrial temperature range compliance (0°C to 70°C). Ensure the package type matches the required 14-pin DIP configuration. Cross-reference pinouts with official documentation to prevent integration errors during PCB layout.

Selection Notes

Select this component when ultra-low drift and high input impedance are critical requirements. It serves as a direct replacement for similar chopper-stabilized amplifiers like the TC7650. Consider its 2 MHz bandwidth and 2.5 V/µs slew rate for applications requiring moderate speed with high DC accuracy. Evaluate power consumption constraints given the 2 mA operating current.

Part Context

This part belongs to the ICL7650 series of chopper-stabilized operational amplifiers. Originally developed by Intersil and later associated with Harris Corporation before Maxim Integrated acquisition, these devices are designed for precision analog applications. The series is known for eliminating low-frequency noise and drift through chopping techniques, making it suitable for instrumentation and measurement circuits.

Replacement Considerations

The TC7650 is documented as a direct replacement for the ICL7650 series. Verify pin compatibility and electrical parameter alignment before substitution. Ensure the alternative component meets the same industrial temperature range and package specifications.
