LT1521CS8

LT1521CS8 is a dual operational amplifier from Linear Technology (now Analog Devices) in an 8-pin CS8 package. It provides precision amplification with low offset voltage and drift, low input bias currents, and low noise, making it suitable for high‑precision signal conditioning. The device contains two op-amps in one package and is used in instrumentation front-ends, active filters, transimpedance stages, sensor conditioning, and audio preamps.
Key points:
- Dual op-amp in an 8‑pin package (CS8 denotes the packaging).
- Designed for precision applications with good offset, drift, and noise performance.
- Suitable for single- or dual-supply operation depending on the variant and configuration.
Usage notes:
- Refer to the LT1521 datasheet for exact electrical characteristics, pinout, and recommended applications.
- Use proper decoupling (e.g., 0.1 µF close to the device) and verify input common‑mode range and stability for your closed-loop configuration.
If you need specific specs (offset, bias current, gain bandwidth, slew rate), check the datasheet for the exact variant.
