CS3002-ISZ

Overview

The CS3002-ISZ is a dual precision low-voltage amplifier manufactured by Cirrus Logic, housed in an 8-lead SOIC surface-mount package. It operates on supply voltages ranging from 2.7V to 6.7V (±1.35V to ±3.35V). Key electrical specifications include a maximum input offset voltage of 10µV and a maximum drift of 0.05µV/°C. The device features a typical open-loop gain of 300dB, a slew rate of 5V/µs, and an input noise density of 6nV/√Hz at 1kHz. It provides rail-to-rail output swing and maintains excellent CMRR and PSRR for DC to 2kHz signal processing.

Feature Summary

Ultra-high open-loop gain architecture designed for precision amplification of low-level signals
Low offset voltage and minimal drift characteristics ensuring long-term stability
Rail-to-rail output capability with low power consumption suitable for battery systems

Applications

Thermocouple and thermopile amplifiers
Load cell and bridge transducer amplifiers
Precision instrumentation circuits
Battery-powered measurement systems

Procurement Notes

Verify the specific ordering suffix 'ISZ' corresponds to the lead-free bulk packaging variant rather than the tape and reel option. Confirm that the industrial temperature range (-40°C to +85°C) aligns with your environmental requirements. Ensure the 8-pin SOIC footprint matches your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when high closed-loop gains are required alongside strict offset and drift limitations. Verify that the application bandwidth remains below 2kHz to maintain optimal performance. Consider adding compensation capacitors if the closed-loop gain exceeds 50V/V or feedback resistors exceed 100Ω to ensure loop stability.

Part Context

This part belongs to the CS3002 family of precision amplifiers from Cirrus Logic. It is specifically engineered for applications demanding superior DC accuracy and low noise. The dual-channel configuration allows for differential signal processing within a compact surface-mount form factor.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation.

FAQ

Is external compensation required for stable operation?

External compensation is not required for closed-loop gains less than or equal to 50V/V with feedback resistors under 100Ω. Compensation capacitors are necessary for higher gains or larger resistor values.
