ICL7621AMTV/BI

Overview

The ICL7621AMTV/BI is a dual CMOS operational amplifier manufactured by Harris Corporation. It features two independent circuits with rail-to-rail output swing capabilities, allowing operation from supply voltages ranging from 2V to 16V. The device exhibits low input bias current of 1pA and an input offset voltage of 5mV. Key electrical parameters include a gain-bandwidth product of 1.4MHz and a slew rate of 1.6V/µs. It operates within a commercial temperature range of 0°C to 70°C and is housed in a TO-99-8 metal can package.

Feature Summary

• Dual-channel CMOS architecture providing independent signal processing paths
• Rail-to-rail output capability for maximum dynamic range utilization
• Ultra-low input bias current suitable for high-impedance sensor interfaces

Applications

• Precision instrumentation amplifiers requiring low drift
• High-impedance buffer stages for transducer signals
• Low-power data acquisition systems

Procurement Notes

Verify the manufacturer designation as Harris Corporation against current Analog Devices or Renesas portfolios due to historical corporate acquisitions. Confirm the specific suffix /BI indicates the required military or extended grade qualification if applicable. Ensure the TO-99-8 metal package availability aligns with current production status, as this form factor may be limited compared to plastic alternatives.

Selection Notes

Select this component when dual-channel performance with rail-to-rail output is required alongside extremely low input bias currents. The TO-99-8 package offers superior thermal and environmental stability compared to standard plastic packages. Consider the 1.4MHz bandwidth limit for high-speed applications where faster slew rates are necessary.

Part Context

The ICL7621 series represents a legacy line of low-power CMOS operational amplifiers originally developed for precision analog applications. Harris Corporation was a primary manufacturer before subsequent industry consolidations transferred intellectual property to other semiconductor entities. This specific variant utilizes a hermetically sealed metal package for enhanced reliability in demanding environments.
