Overview
The ICL7650CSD+T is a chopper-stabilized operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features a unity-gain bandwidth of 2 MHz and a slew rate of 2.5 V/µs. The device operates on a supply voltage range of 4.5V to 16V with a typical supply current of 3.5 mA. Key electrical characteristics include an input offset voltage of ±10 µV, an input bias current of 10 pA, and a common-mode rejection ratio of 120 dB. It is housed in an 8-pin SO package.
Feature Summary
- Chopper-stabilized architecture providing continuous error correction for minimal drift
- Low input offset voltage and low input bias current for high precision
- High gain common-mode rejection ratio and power-supply rejection ratio
- Internal oscillator or external clock operation capability
Applications
- Condition Amplifier
- Precision Amplifier
- Instrumentation Amplifier
- Thermocouples
- Strain Gauges
Procurement Notes
Verify the specific suffix 'CSD' corresponds to the 8-pin SO package and commercial temperature range (0°C to +70°C) as listed in the ordering information. Confirm that the '+T' indicates tape-and-reel packaging if required for assembly. Check for RoHS compliance status associated with the '+' designation against current manufacturer documentation.
Selection Notes
Select this component for applications requiring low-level signal processing where extremely low drift over time and temperature is critical. The ICL7650 offers lower supply current compared to previous generations while maintaining high performance. Consider the 8-pin SO package constraints regarding pin availability for nulling capacitors compared to the 14-pin version.
Part Context
This device belongs to the ICL7650/ICL7653 family of chopper-stabilized amplifiers. It serves as an improved second source to Intersil's ICL7650B/53B. The ICL7650 specifically includes an output clamp circuit to minimize overload recovery time, distinguishing it from the ICL7653 which lacks this feature but offers slightly lower noise.
Replacement Considerations
The datasheet identifies the ICL7650B as an exact replacement for Intersil’s ICL7650B. Verify pin compatibility with industry-standard 8-pin devices like the LM741 or LM101, noting that external null storage capacitors connect to pins 1 and 8.
