ICL7621DMTV

Overview

The ICL7621DMTV is a dual-channel CMOS operational amplifier manufactured by Harris Corporation. It features rail-to-rail output capability and operates within a supply voltage range of 1V to 16V. Key electrical parameters include a gain-bandwidth product of 1.4 MHz, a slew rate of 1.6 V/µs, and an input bias current of 1 pA. The device is housed in a TO-99-8 metal can package and supports an extended operating temperature range from -55°C to +125°C.

Feature Summary

• Dual-channel CMOS architecture providing two independent amplifier circuits
• Rail-to-rail output swing for maximum dynamic range utilization
• Extended industrial temperature rating suitable for harsh environments

Applications

• Precision instrumentation systems requiring low bias current
• Battery-powered devices utilizing wide single-supply voltage ranges
• Harsh environment sensor signal conditioning

Procurement Notes

Verify the manufacturer origin carefully, as the ICL7621 series was originally developed by Maxim Integrated (now Analog Devices). Ensure the specific DMTV suffix corresponds to the Harris Corporation TO-99-8 metal can package variant rather than standard plastic packages. Confirm RoHS compliance status and lot traceability requirements before finalizing procurement orders.

Selection Notes

Select this component when high reliability and radiation hardness are required due to the hermetic metal can packaging. The rail-to-rail output and low input bias current make it suitable for high-impedance source applications. Compare against modern CMOS op-amps if lead times for legacy Harris parts are prohibitive or if lower power consumption is critical.

Part Context

This part belongs to the ICL7621 family of dual CMOS operational amplifiers. While often associated with Maxim Integrated, the DMTV variant specifically denotes the Harris Corporation production run in a TO-99-8 package. This family is known for combining CMOS low power characteristics with robust performance metrics.

Replacement Considerations

Direct replacements may be limited due to the specific TO-99-8 metal can package. Consider equivalent dual CMOS op-amps in compatible packages such as SOIC-8 or DIP-8 if pinout compatibility allows, ensuring similar gain-bandwidth and bias current specifications.
