INA826AID

The INA826AID is a precision instrumentation amplifier with rail to rail output in 8 pin SOIC package. This low cost instrumentation amplifier offers extremely low power consumption and operates over a very wide single or dual supply range. A single external resistor sets any gain from 1 to 1000. It offers excellent stability over temperature even at gain greater than 1 as a result of low gain drift of only 35ppm/°C (maximum). The INA826 is optimized to provide excellent common mode rejection ratio of over 100dB (G = 10) over frequencies up to 5KHz. Using a rail to rail output, the INA826 is well suited for low voltage operation from 2.7V single supply as well as dual supplies up to ±18V. Additional circuitry protects the inputs against overvoltage of up to ±40V beyond the power supplies by limiting input currents to less than 8mA.

• Supply current of 200µA
• Single supply voltage range from 2.7V to 36V and dual supply voltage range from ±1.35V to ±18V
• Low offset voltage of 150µV
• Input stage voltage noise of 18nV/√Hz at G ≥ 100
• -3db bandwidth of 1MHz at G = 1
• Inputs protected up to ±40V
• Slew rate of 1V/μs
• Operating temperature range from -40°C to 125°C
