Texas Instruments INA828 Precision Instrumentation Amplifiers
Texas Instruments INA828 50μV Offset, 7nV/√Hz Noise, Low-Power, Precision Instrumentation Amplifiers operate over a very wide single- or dual-supply range and provides low power consumption. The device sets any gain from 1 to 1000 with a single external resistor. Super-beta input transistors provide exceptionally low input offset voltage, offset voltage drift, input bias current, and input voltage and current noise through the device offering excellent precision.
The device offers additional circuitry that protects the inputs against overvoltage up to ±40V. The INA828 is optimized to create an excellent common-mode rejection ratio, at G=1, the common-mode rejection ratio exceeds 90dB across the full input common-mode range.
Dual supplies up to ±18V and 5V single supply make the device suitable for low-voltage operation. The INA828 is specified over the –40°C to +125°C temperature range and is available in an 8-pin SOIC package.
