The AD524 is a precision instrumentation amplifier from Analog Devices. It features low noise, low nonlinearity, high CMRR, low offset voltage, low offset voltage drift, high gain bandwidth product and pin programmable gains of 1, 10, 100, 1000. It also has input protection, switch mode power supply and no external components required.
The AD524 is a precision monolithic instrumentation amplifier offering low noise, low offset voltage drift, and high CMRR. It features pin‑programmable gains of 1, 10, 100, and 1000, with the ability to set any gain between 1 and 1000 using a single external resistor. The device is fully protected for power‑on and power‑off fault conditions and requires no external components for the fixed gain settings.
The datasheet includes detailed electrical specifications, absolute maximum ratings, connection diagrams, and typical performance characteristics. It also lists the available package options (16‑lead ceramic DIP, SOIC, and 20‑terminal leadless chip carrier) and ordering information for the AD524 family (A, B, C, S grades).
