CS3002-ISZ

Instrumentation, Op Amps, Buffer Amps 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.

Instrumentation, Op Amps, Buffer Amps 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.

Instrumentation, Op Amps, Buffer Amps 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.

Instrumentation, Op Amps, Buffer Amps 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.

What is the common mode input voltage range?

The common mode input range includes the negative supply rail, extending up to approximately 1.25V below the positive supply voltage.
