Overview
The ICL7621BCSA+T is a dual-channel monolithic CMOS operational amplifier from the ICL761X–ICL764X family. It features an input bias current of 50pA maximum and an input offset voltage of 10mV maximum at +25°C. The device operates on supply voltages ranging from ±1V to ±8V or single supplies from 2V to 16V, with a quiescent current of 15µA per amplifier. It utilizes an 8-pin Slim Small Outline (SO) package and supports a commercial operating temperature range of 0°C to +70°C.
Feature Summary
- Monolithic low-power CMOS design
- Ultra-low input bias current
- Wide supply voltage operation
- Rail-to-rail output swing
Applications
- Long-time constant integrators
- Picoammeters
- Low droop rate sample/hold amplifiers
- pH meters
- Photodiode amplifiers
Procurement Notes
Verify that the ordering suffix matches the specific package and temperature grade requirements for your application. Confirm RoHS compliance status as indicated by the plus sign in the part number. Ensure the supplier provides official documentation matching the Analog Devices / Maxim Integrated datasheet specifications before finalizing procurement.
Selection Notes
Select this component when ultra-low input bias currents are critical for high-impedance source applications. The dual configuration allows for cost-effective implementation of differential circuits. Verify that the required bandwidth and slew rate align with the fixed quiescent current characteristics of the dual amplifier variant.
Part Context
This part belongs to the ICL761X–ICL764X family of precision operational amplifiers manufactured by Analog Devices / Maxim Integrated. The 'B' designation indicates a specific input offset voltage grade, while 'C' denotes the commercial temperature range. The 'SA' suffix identifies the 8-pin Slim Small Outline package format.
Replacement Considerations
Check for pin-compatible alternatives within the same ICL76XX series family. Verify that substitute parts maintain equivalent input bias current and offset voltage specifications to ensure circuit performance integrity without redesigning the surrounding components.
