DESCRIPTION

· The TPA1286 is a cost-effective, wide supply range instrumentation amplifier.

· It requires only one external resistor to set a gain between 1 and 1,000.

· Designed for single voltage operations with a wide input range and rail-to-rail output.

· Features low voltage offset, low offset drift, low gain drift, high gain accuracy, and high CMRR.

· Operates from a single 4V to 36V supply and performs excellently from -40°C to +125°C.

· Available in SOP8, MSOP8, and DFN3X3-8 packages.

FEATURES

· Excellent DC specifications: ±50uV max voltage offset, 0.2μV/°C max drift, 1.5nA max input bias current.

· Superior AC specifications: 80dB CMRR at G=1, 15nV/√Hz input noise at G=10, 1μV p-p input noise (0.1Hz to 10Hz).

· 1.6MHz -3dB bandwidth and 5V/μs slew rate.

· Gain adjustable from 1 to 1,000 with one external resistor.

· Supply voltage range: ±2V to ±18V.

· Rail-to-rail voltage output.

· Operating temperature: -45°C to +125°C.

· Available in SOP8, MSOP8, and DFN3X3-8 packages.
