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.
