3 Description
INA351 is a selectable-gain instrumentation amplifier
with integrated reference buffer that offers four gain
options across INA351ABS and INA351CDS variants
available in small packages. INA351ABS has gain
options of 10 or 20 and INA351CDS has gain options
of 30 or 50. These gain options can be selected
by toggling the gain select (GS) pin. INA351 is
an excellent choice for bridge-type sensing and for
differential to single-ended conversion applications.
Built with precision matched integrated resistors,
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 (ADC) 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, INA351
is optimized for delivering performance. The device
achieves 86 dB of minimum CMRR and an accurate
0.1 of maximum gain error, along with 1.3 mV
of maximum offset across all gain options, while
consuming just 135 μA of maximum quiescent
current. INA351 has an integrated shutdown option
to turn off the amplifier when idle for additional power
savings in battery powered applications.
