Description
The INA128 is a low-power general purpose instrumentation amplifier that offers excellent precision.
The versatile 3-operation amplifier design and small size make these amplifiers ideal for a wide range of applications. Current feedback input circuits provide a wide bandwidth even with high gain (200 kHz to g = 100). A single external resistor sets any gain from 1 to 10,000.
The INA128 provides an industry standard gain equation; The INA128 gain equation is compatible with the AD620. and high common mode rejection (120 dB in g ≥ 100). The INA128 works with power supplies as low as ± 2.25 V and the quiescent current is only 700 μA, ideal for battery operated systems. Internal input protection can support up to ± 40 V without damage.
