Overview
The ICL7650CSA+T is a chopper-stabilized operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features a maximum input offset voltage of 10µV and a maximum input bias current of 20pA over the commercial temperature range. The device operates on a supply voltage between 4.5V and 16V with a typical supply current of 3.5mA. Key electrical parameters include a unity-gain bandwidth of 2MHz, a slew rate of 2.5V/µs, and minimum common-mode rejection and power-supply rejection ratios of 120dB. It is housed in an 8-pin SO package.
Feature Summary
- Chopper-stabilized architecture providing continuous error correction to minimize input offset voltage across the operating temperature range.
- Integrated output clamp circuit designed to reduce overload recovery time inherent in chopper-stabilized amplifiers.
- Monolithic low-power CMOS design ensuring low DC input bias current and extended common-mode voltage range.
Applications
- Condition Amplifier
- Precision Amplifier
- Instrumentation Amplifier
- Thermocouples
- Strain Gauges
Procurement Notes
Verify that the component matches the specific ICL7650CSA+T designation, as the datasheet lists ICL7650CSA without the suffix. Confirm the manufacturer is Analog Devices Inc./Maxim Integrated. Ensure the package type corresponds to the 8-pin SO format specified for this part number variant.
Selection Notes
Select this component for applications requiring ultra-low drift and high precision DC amplification where traditional trimming is impractical. The internal nulling scheme eliminates the need for external offset adjustment components. Consider the 2MHz bandwidth and 2.5V/µs slew rate for signal processing requirements within these limits.
Part Context
This device belongs to the ICL7650 family of chopper-stabilized amplifiers. It serves as an improved second source to Intersil's ICL7650B. The ICL7650 variant specifically includes an output clamp pin (Pin 5) for enhanced overload recovery, distinguishing it from the ICL7653 which lacks this feature but offers slightly lower noise.
Replacement Considerations
The ICL7650BCSA is listed as an exact replacement for Intersil’s ICL7650B. Verify if the ICL7653 can be used if the output clamp functionality is not required, noting differences in noise performance and pinout compatibility with standard industry devices like the LM741.
