The device is optimized for the lowest possible gain drift of only 1 ppm 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 mon-mode rejection ratio (CMRR) of over 88 d B (G = 5) over frequencies up to 5 k Hz. In G = 5, CMRR exceeds 88 d B across the full input monmode range from the negative supply all the way up to 1 V of the positive supply. Using a rail-to-rail output, the INA827 is well-suited for low-voltage operation from a 3-V singlesupply 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 a save level. The INA827 is available in a small VSSOP-8 package and is specified for the - 40°C to +125°C temperature range. For a similar instrumentation amplifier with a gain range of 1 V/V to 1000 V/V, see the INA826. Device Information(1) PART NUMBER PACKAGE BODY...
