INA826AIDR

Description

The INA826 is a cost-effective instrumentation amplifier that offers extremely low power consumption and operates over a very wide single-supply or dualsupply range. A single external resistor sets any gain from 1 to 1000. The device offers excellent stability over temperature, even at G > 1, as a result of the low gain drift of only 35 ppm/°C (maximum).
