Product Details

The AD8236 is the lowest power instrumentation amplifier in the industry. It has rail-to-rail outputs and can operate on voltages as low as 1.8 V. Its 40 μA maximum supply current makes it an excellent choice in battery-powered applications.

The AD8236’s high input impedance, low input bias current of 1 pA, high CMRR of 110 dB (G = 100), small size, and low power offer tremendous value. It has a wider common-mode voltage range than typical three-op-amp instrumentation amplifiers, making this a great solution for applications that operate on a single 1.8 V or 3 V supply. An innovative input stage allows for a wide rail-to-rail input voltage range without the crossover distortion common in other designs.

The AD8236 is available in an 8-lead MSOP and is specified over the industrial temperature range of −40°C to +125°C

    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.
