1. Describe

INA828IDR is a high precision instrument amplifier that provides low power consumption and Operates on a very wide single or dual supply scope. A single external resistor sets any gain to 1 to 1000. The device provides excellent accuracy due to Using the new ultra-beta input transistors, Provides very low input offset voltage, offset voltage drift, input bias current and input voltage and current noise. Additional circuit protection input Resistant to overvoltages up to ±40 V. The INA828 is optimized to provide excellent Common Mode Rejection Ratio. CMRR exceeds 90 dB at G = 1 Enter the common mode range. The device is perfect for Low Voltage Operation for 5V Single Supply and dual power supplies up to ±18 V. Finally, the INA828 is Available in 8-pin SOIC package and specified Over the temperature range of –40°C to +125°C.
