The INA351 is a selectable-gain instrumentation amplifier with integrated reference buffer that offers four gain options across the INA351ABS and INA351CDS variants available in small packages. The INA351ABS has gain options of 10 or 20 and the INA351CDS has gain options of 30 or 50. These gain options can be selected by toggling the gain select (GS) pin. The INA351 is an excellent choice for bridge-type sensing and for differential to single-ended conversion applications.

Built with precision matched integrated resistors, the INA351 saves on BOM costs, pick-and-place machine handling costs, and board space by removing the need for precise or closely-matched external resistors. The INA351 can interface directly to low-speed, 10-bit to 14-bit, analog-to-digital converters (ADCs) and is an excellent choice for replacing discrete implementation of instrumentation amplifiers built with commodity amplifiers and discrete resistors.

Designed with the three-amplifier architecture, the INA351 is optimized for delivering performance. The device achieves 86dB of minimum CMRR and an accurate 0.1% of maximum gain error, along with 1.3mV of maximum offset across all gain options, while consuming just 135µA of maximum quiescent current. The INA351 has an integrated shutdown option to turn off the amplifier when idle for additional power savings in battery-powered applications.
