Texas Instruments INA350 Low-Power Instrumentation Amplifier is a selectable-gain instrumentation amplifier that offers four gain options across INA350ABS and INA350CDS variants available in small packages. INA350ABS has gain options of 10 or 20, and INA350CDS has gain options of 30 or 50. These gain options can be selected by toggling the gain select (GS) pin. INA350 is ideal for bridge-type sensing and differential to single-ended conversion applications.
Built with precision matched integrated resistors, INA350 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 device interfaces directly to low-speed, 10-bit to 14-bit, analog-to-digital converters (ADC) and is ideal for replacing the discrete implementation of instrumentation amplifiers built with commodity amplifiers and discrete resistors.
Texas Instruments INA350 is optimized for performance and designed with the three-amplifier architecture. It achieves 85dB of minimum CMRR and 0.6% of maximum gain error, along with 1.2mV of maximum offset across all gain options, while consuming just 125µA of maximum quiescent current. It has an integrated shutdown option to turn off the amplifier when idle for additional power savings in battery-powered applications.
