Product Details

The AD8223 is an integrated single-supply instrumentation amplifier that delivers rail-to-rail output swing on a single supply (3 V to 24 V). The AD8223 conforms to the 8-lead industry standard pinout configuration

The AD8223 is simple to use: one resistor sets the gain. With no external resistor, the AD8223 is configured for G = 5 and with an external resistor, the AD8223 can be programmed for gains up to 1000.

The AD8223 has a wide input common-mode range and can amplify signals that have a 150 mV common-mode voltage below ground. Although the design of the AD8223 is optimized to operate from a single supply, the AD8223 still provides excellent performance when operated from a dual voltage supply (±2 V to ±12 V).

Low power consumption (1.5 mW at 3 V), wide supply voltage range, and rail-to-rail output swing make the AD8223 ideal for battery-powered applications. The rail-to-rail output stage maximizes the dynamic range when operating from low supply voltages. The AD8223 replaces discrete instrumentation amplifier designs and offers superior linearity, temperature stability, and reliability in a minimum of space.

    Tools & Simulations

    In-Amp Diamond Plot Tool

    The Diamond Plot Tool is a web application that generates a configuration-specific Output Voltage Range vs. Input Common-Mode Voltage graph, also known as the Diamond Plot, for Analog Devices Instrumentation Amplifiers. Based on user inputs such as supply voltage, gain, and input signal range, the tool detects saturation and recommends in-amps for which the input signal is in-range and the configuration is valid. Avoid saturation, find the best in-amp for your design, and save time.
