INA827EVM Datasheet PDF - TI

The INA827EVM is intended to provide basic functional evaluation of the INA827. The INA827 is a low cost instrumentation amplifier that offers extremely low power consumption and operates over a very wide single or dual supply range. The device is optimized for the lowest possible gain drift of only 1ppm per degree Celsius in G = 5, which requires no external resistor. However, a single external resistor sets any gain from 5 to 1000. The INA827 is optimized to provide excellent common mode rejection ratio of over 88 dB (G = 5) over frequencies up to 5kHz. In G = 5, CMRR exceeds 88dB across the full input common-mode range from the negative supply all the way up to 1V of the positive supply. Using a rail to rail output, the INA827 is well suited for low voltage operation from a 2.7V single supply as well as dual supplies up to ±18V. Additional circuitry protects the inputs against overvoltage of up to ±40 V beyond the power supplies by limiting the input currents to a save level.

● Intuitive evaluation with the silkscreen schematic

● Easy access to nodes with surface-mount test points

● Advanced evaluation with two prototype areas

● Reference voltage source flexibility

● Convenient input and output filtering

●It is important to operate this EVM within the input voltage range of -18V to 17V and the output voltage range of -14V to 14V. Exceeding the specified input range may cause damage to the EVM.
