Analog Devices AD8229 Instrumentation Amplifier Datasheet
The AD8229 is a low-noise instrumentation amplifier designed for measuring small signals in high common-mode voltage and high-temperature environments. It features industry-leading 1 nV/√Hz input noise performance and a high common-mode rejection ratio (CMRR) that improves with gain. The device is specifically engineered for harsh environments, such as downhole instrumentation and exhaust gas measurement, utilizing a dielectric isolation process to prevent leakage currents at elevated temperatures.
The amplifier supports a wide operating temperature range of -40°C to +210°C for SBDIP packages and -40°C to +175°C for SOIC packages. It offers a gain range from 1 to 1000 set by a single external resistor and includes a reference pin for output level shifting. The document provides comprehensive electrical specifications, absolute maximum ratings, typical performance characteristics, and application guidelines. This manual is written in Chinese.
