Overview
The TPA1287 is a low-cost, wide supply range instrumentation amplifier that requires only one external resistor to set any gain between 1 and 1,000. The TPA1287 is designed to work with a variety of single voltages. A wide input range and rail-to-rail output allow the signal to fully use the supply rails. Low voltage offset, low offset drift, low gain drift, high gain accuracy, and high CMRR make this part an excellent choice in applications that demand the best DC performance.
The TPA1287 operates from a single 4-V to 36-V supply, and offers breakthrough performance throughout the −40°C to +125°C temperature range. It features a zerodrift core, which leads to the offset drift of 0.2 μV/°C throughout the operating temperature range.
The TPA1287 is available in SOP8 and MSOP8 packages.
