Kit Overview

The Evaluation Module INA826EVMINA826EVM is designed to evaluate the performance of the INA826INA826 device in both single and dual-supply configurations.

The INA826INA826 is a low-cost instrumentation amplifier that 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 G > 1, as a result of the low gain drift of only 35 ppm/°C (max).

The INA826INA826 is optimized to provide excellent common-mode rejection ratio of over 100 dB (G = 10) over frequencies up to 5 kHz. In G = 1, the common-mode rejection ratio exceeds 84 dB across the full input common-mode range from the negative supply all the way up to 1 V of the positive supply. Using a rail-to-rail output, the INA826 is well-suited for low voltage operation from a 2.7 V single supply as well as dual supplies up to ±18 V.

Additional circuitry protects the inputs against overvoltage of up to ±40 V beyond the power supplies by limiting the input currents to less than 8 mA.

The INA826INA826 is available in SO-8, MSOP-8, and tiny 3-mm × 3-mm DFN-8 surface-mount packages. All versions are specified for the –40°C to +125°C temperature range.

Key Applications: Industrial Process Controls, Circuit Breakers, Battery Testers, ECG Amplifiers, Power Automation, Medical Instrumentation, Portable Instrumentation.
