Description for the INA823
The INA823 is an integrated instrumentation amplifier that offers low power consumption and operates over a wide, single-supply or dual-supply range. A single external resistor sets any gain from 1 to 10,000. The device provides low input offset voltage, low offset voltage drift, low input bias current, and low current noise while remaining cost-effective. Additional circuitry protects the inputs against overvoltage up to ±60 V.
The INA823 is optimized to provide a high common-mode rejection ratio. At G = 1, the common-mode rejection ratio exceeds 84 dB across the full input common-mode range. The INA823 has a wide common-mode voltage range as low as 150-mV below negative supply. The device is designed for low-voltage operation from a 2.7-V single supply, and dual supplies up to ±18 V. The low power and single supply operation enable hand-held, battery-operated systems.
