CS3012-ISZ

Instrumentation, Op Amps, Buffer Amps Overview

The CS3012-ISZ is a dual precision low-voltage operational amplifier designed for DC to 1 kHz applications. It features a maximum input offset voltage of ±10 µV and an average drift of ±0.05 µV/°C. The device offers a typical open-loop gain of 300 dB, a slew rate of 2 V/µs, and an input noise density of 12 nV/√Hz at 1 kHz. Operating from a supply voltage range of 2.7 V to 6.7 V, it consumes 2.4 mA per amplifier. The component is housed in an 8-lead SOIC package.

• Features rail-to-rail output swing capability and includes the negative supply rail within the common mode input range.
• Utilizes a patented architecture yielding very high open-loop gain specifically optimized for frequencies of 1 kHz and below.

Instrumentation, Op Amps, Buffer Amps Applications

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

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix ISZ indicates lead-free construction and compliance with RoHS standards. Confirm the operating temperature range covers -40°C to +85°C for your environment. Check current availability status as components may be subject to discontinuation or lifecycle changes. Ensure the 8-lead SOIC package dimensions match your PCB footprint requirements before finalizing orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high closed-loop gains are required for low-frequency signals. It is suitable for designs needing low noise and minimal offset drift over time and temperature. Consider using external compensation capacitors if the closed-loop gain exceeds 50 V/V to maintain stability. Verify that the application bandwidth remains below 1 kHz to utilize the optimal gain characteristics.

Instrumentation, Op Amps, Buffer Amps Part Context

The CS3012-ISZ belongs to the CS301x series of precision amplifiers manufactured by Cirrus Logic. This family includes the single-channel CS3011 and the dual-channel CS3012 variants. These devices share identical electrical specifications and architectural features, differing only in the number of integrated amplifier channels within the package.
