3PEAK TPA1286U-DF7R

TPA1286 is a low-cost, wide supply voltage range instrumentation amplifier that requires only a single external resistor to set any gain between 1 and 1,000. The device is designed for operation across a variety of single-supply voltages. Its wide input range and rail-to-rail output allow signals to make full use of the supply rails. Low voltage offset, low offset drift, low gain drift, high gain accuracy, and high common-mode rejection ratio make it an ideal choice for applications demanding DC performance. The TPA1286 operates from a single supply of 4V to 36V and delivers breakthrough performance over the full temperature range of -40°C to +125°C. It employs a zero-drift core with a typical offset drift of 0.2μV/°C across the entire operating temperature range. The TPA1286 is available in SOP8, MSOP8, and DFN3X3-8 packages.
