ICL7621DCPA

Overview

The ICL7621DCPA is a dual operational amplifier from the Renesas Electronics Corporation ICL7621 series. It features two channels in an 8-pin PDIP package designed for through-hole installation. The device operates within a supply voltage range of 3 V to 8 V and supports a gain-bandwidth product of 480 kHz. Key electrical characteristics include a maximum input offset voltage of 20 mV, an input bias current of 800 pA, and a slew rate of 0.16 V/μs. It functions reliably across an operating temperature range from 0°C to 70°C.

Feature Summary

• Dual-channel architecture providing two independent operational amplifiers in a single component.
• CMOS technology enabling low power consumption suitable for battery-operated applications.
• Internal frequency compensation eliminates the need for external components.

Applications

• General-purpose signal conditioning circuits
• Low-power sensor interface designs
• Active filter implementations

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm pinout compatibility and thermal specifications. Ensure the procurement channel provides traceable manufacturing data. Confirm RoHS compliance status matches project requirements. Cross-reference the manufacturer date code with current production status to avoid obsolete stock issues during long-term deployment.

Selection Notes

Select this component when a dual-channel solution is required with moderate bandwidth and low bias current. Compare the 480 kHz gain-bandwidth product against application signal frequencies. Evaluate the 800 pA input bias current against source impedance requirements to minimize offset errors. Verify that the 8-pin DIP package fits the target PCB layout constraints.

Part Context

This part belongs to the ICL7621 family of dual CMOS operational amplifiers originally developed by Intersil and now manufactured by Renesas Electronics. The series is characterized by its low power consumption and internal compensation. The DCPA designation specifically indicates the dual-channel variant housed in a standard plastic dual in-line package for through-hole mounting.
