AD522 is a precision instrumentation amplifier gold pin

Specifications and Function

​Manufacturer: The triangle-and-bar logo is the classic mark for Analog Devices (AD), a well-known manufacturer of integrated circuits.

​Part Number: AD522BD

​Function: The AD522 is a precision instrumentation amplifier. These types of amplifiers are specifically designed for applications that require high precision and stability, such as measuring very small signals in the presence of large common-mode voltages.

​"BD" Suffix: The "BD" suffix typically refers to a specific package and operating temperature range. For Analog Devices parts from this era, "B" would often indicate a hermetic ceramic dual in-line package (DIP) and a military-grade temperature range, while "D" could specify a certain level of performance or a specific package variant. The hermetic package (the metal can) protects the sensitive internal circuitry, making it suitable for harsh environments.

​Date Code: The "8302" marking indicates the component was manufactured in the 2nd week of 1983.

​Country of Origin: USA.
