ICL7632BCPE

Overview

The ICL7632BCPE is a triple operational amplifier from the ICL761X–ICL764X family, manufactured by Analog Devices Inc./Maxim Integrated. It utilizes monolithic CMOS technology and features pin-selectable quiescent currents of 10μA, 100μA, or 1000μA per amplifier. The device operates from ±1V to ±8V power supplies or single supplies from 2V to 16V. Key electrical parameters include a unity-gain bandwidth of 0.044 MHz at 10μA IQ, an input bias current of 1pA typical, and a maximum input offset voltage of 5mV for the B grade. It is housed in a 16-lead Plastic DIP package with a commercial temperature range of 0°C to +70°C.

Feature Summary

• Ultra-low input bias current of 1pA typical, ensuring minimal loading on high-impedance sources
• Pin-selectable quiescent current allows optimization between low power consumption and higher bandwidth/slew rate
• CMOS outputs swing to within millivolts of supply rails, enabling rail-to-rail output capability
• Input offset nulling capability via external potentiometer connection

Applications

• Long time constant integrators
• Picoammeters
• Low-frequency active filters
• Low-leakage amplifiers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm the exact package type, temperature range, and electrical grade. Ensure the component matches the required quiescent current configuration for your application. Cross-reference the part number with authorized distributors to confirm availability and authenticity. Check for any lead-free or RoHS compliance markings if required by your manufacturing standards.

Selection Notes

Select this component when ultra-low input bias current is critical for signal integrity. The triple configuration offers three independent amplifiers in one package. Consider the trade-off between quiescent current settings: lower IQ reduces power but decreases bandwidth and slew rate. Verify that the extended common-mode voltage range requirements are met, as this varies by specific sub-model within the family.

Part Context

This part belongs to the ICL761X–ICL764X family of monolithic CMOS operational amplifiers. The '7632' designation indicates a triple amplifier configuration. The 'B' suffix denotes a specific input offset voltage grade (max 5mV). The 'C' indicates the commercial temperature range (0°C to +70°C), and 'PE' specifies the 16-lead Plastic DIP package. This family is known for its programmable power consumption and high input impedance.

Replacement Considerations

Direct pin-for-pin replacements within the same family include other ICL763x variants with different offset grades (e.g., ICL7632ACPE, ICL7632DCPE) or temperature ranges (e.g., ICL7632BMJE). Ensure the replacement maintains the required quiescent current programming capability and package compatibility.
