Description
General part information
INA350 Series
INA350 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 for differential to single-ended conversion applications.
Built with precision matched integrated resistors, INA350 saves on bill of materials (BOM) costs, pick-and-place machine handling costs, and board space by removing the need for precise or closely-matched external resistors. The device interface directly to low-speed, 10-bit to 14-bit, analog-to-digital converters (ADC) and is ideal for replacing discrete implementation of instrumentation amplifiers built with commodity amplifiers and discrete resistors.
Designed with the three-amplifier architecture, INA350 is optimized for delivering performance. It achieves 85 dB of minimum CMRR and 0.6% of maximum gain error, along with 1.2 mV of maximum offset across all gain options, while consuming just 125 µA 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.
