Precision Op Amps

Analog Devices’ broad range of precision operational amplifiers (op amps) provides industry-leading support to designers in need of traditional trimmed and zero-drift amplifier technology. Our precision op amp family helps preserve the accuracy of DC information in an incoming signal with low offset voltage (Vos < 1 mV) and low temperature drift characteristics (TCVos < 2 μV/°C).

Zero-Drift Op Amps

The latest zero-drift operational amplifiers (op amps) from Analog Devices combine both auto-zero and chopping techniques to continuously self-correct for DC errors over time and temperature. This enables the op amps to achieve <4 µV of input offset error and input drift error of <20 nV/°C. By design, zero-drift op amps have no 1/f voltage noise, nor do they suffer from long-term drift, making them ideal for low speed sensing. By reducing the drift and noise, these products decrease the need for constant system-level calibration. Additionally, very small LFCSP packages reduce board space, and on-chip electromagnetic interference filters speed development time by eliminating the need for collaboration circuitry. They accomplish all these features while controlling cost. ADI’s zero-drift op amp portfolio is an ideal choice for high performance projects and in products that are required to have a long lifecycle.
