The INA819 is a high-precision
instrumentation amplifier that offers low power consumption and operates over a very
wide single-supply or dual-supply range. A single external resistor sets any gain
from 1 to 10,000. The device offers high precision as a result of super-beta input
transistors, which provide exceptionally low input offset voltage, offset voltage
drift, input bias current, input voltage, and current noise. Additional circuitry
protects the inputs against overvoltage up to ±60 V.
The INA819 is optimized to provide a
high common-mode rejection ratio. At G = 1, the common-mode rejection ratio exceeds
90 dB across the full input common-mode range. The device is designed for
low-voltage operation from a 4.5-V single supply, as well as dual supplies up to ±18
V.
The INA819 is available in 8-pin SOIC,
VSSOP, and WSON packages, and is specified over the –40°C to +125°C temperature
range.
