The AD8231 is a low drift, rail-to-rail, instrumentation amplifier with software-programmable gains of 1, 2, 4, 8, 16, 32, 64, or 128. The gains are programmed via digital logic or pin strapping.The AD8231 is ideal for applications that require precision performance over a wide temperature range, such as industrial temperature sensing and data logging. Because the gain setting resistors are internal, maximum gain drift is only 10 ppm/°C for gains of 1 to 32. Because of the auto-zero input stage, maximum input offset is 15 μV and maximum input offset drift is just 50 nV/°C. CMRR is 80 dB for G = 1, increasing to 110 dB at higher gains.The AD8231 also includes an uncommitted op amp that can be used for additional gain, differential signal driving, or filtering. Like the in-amp, the op amp has an auto-zero architecture, rail-to-rail input, and rail-to-rail output.The AD8231 includes a shutdown feature that reduces current to a maximum of 1 μA. In shutdown, both amplifiers also have a high output impedance, which allows easy multiplexing of multiple amplifiers without additional switches.The AD8231 is specified over the extended industrial tempera-ture range of −40°C to +125°C. It is available in a 4 mm × 4 mm 16-lead LFCSP.Applications Pressure and strain transducers Thermocouples and RTDs Programmable instrumentation Industrial controls Weigh scales Automotive controls

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°CApplicationsMedical instrumentationLow-side current sensePortable devices
