Design INA828
SBOS792A – AUGUST 2017 – REVISED JANUARY 2018 INA828 50-µV Offset, 7-nV/√Hz Noise, Low-Power, Precision Instrumentation Amplifier
1 Features 3 Description The INA828 is a high-precision instrumentation
amplifier that offers low power consumption and
operates over a very wide single-or dual-supply
range. A single external resistor sets any gain from 1
to 1000. The device offers excellent precision due to
the use of new super-beta input transistors which
provide exceptionally low input offset voltage, offset
voltage drift, input bias current, and input voltage and
current noise. Additional circuitry protects the inputs
against overvoltage up to В±40 V. 1 Precision Instrumentation Amplifier Evolution:
– Second Generation: INA828
– First Generation: INA128
Low Offset Voltage: 50 ВµV, MAX
Gain Drift: 5 ppm/В°C (G = 1), 50 ppm/В°C (G > 1)
Noise: 7 nV/в€љHz …
