ICL7621AMTV

Overview

The ICL7621AMTV is a dual, low-power CMOS operational amplifier manufactured by Intersil. It features an industry-standard pinout and operates on wide supply voltages ranging from ±1V to ±8V or single supplies up to 16V. The device utilizes a monolithic CMOS design with an input impedance of 10^12 ohms, resulting in extremely low input bias current. Key electrical parameters include a gain-bandwidth product of 480 kHz, a slew rate of 160 mV/µs, and a maximum input offset voltage of 3 mV. It is housed in an 8-lead TO-99 metal can package.

Feature Summary

• Monolithic low-power CMOS architecture providing high input impedance
• Industry-standard pinouts for direct replacement compatibility
• Wide supply voltage range supporting both dual and single power sources

Applications

• Long-time constant integrators
• Picoammeters
• Low droop rate sample/hold amplifiers
• Battery-powered instruments

Procurement Notes

Verify the specific suffix 'MTV' against the manufacturer's official datasheet to confirm the package type and temperature grade. Ensure the component matches the required operating temperature range and that the source documentation explicitly identifies the part as a dual operational amplifier. Cross-reference the manufacturer designation to confirm Renesas or Intersil origin.

Selection Notes

Select this component when designing circuits requiring ultra-low input bias currents and high input impedance. It is suitable for applications where low power consumption is critical alongside moderate bandwidth requirements. Verify that the TO-99 package form factor fits the mechanical constraints of the target PCB or chassis assembly.

Part Context

The ICL7621 belongs to the ICL762X series of dual operational amplifiers. This family is characterized by its CMOS construction, which enables very low quiescent current draw compared to bipolar counterparts. The series is widely recognized for its stability and reliability in precision analog signal processing tasks within commercial and industrial environments.

Replacement Considerations

Check for equivalents such as the ICL7621ACSA+ or ICL7621DCPAZ. Confirm that substitute parts maintain the same 8-pin configuration and meet the original electrical specifications for offset voltage and bandwidth.
