The INA128 and INA129 are low power, general purpose instrumentation amplifiers offering excellent

accuracy. Their versatile 3-op amp design and small size make them ideal for a wide range of applications.

Current-feedback input circuitry provides wide bandwidth even at high gain (200kHz at G = 100). A single external resistor sets any gain from 1 to 10,000. INA128 provides an industry standard gain equation; INA129’s gain equation is compatible with the AD620. The INA128/INA129 is laser trimmed for very low

offset voltage (50μV), drift (0.5μV/°C) and high common-mode rejection (120dB at G ≥ 100). It operates

with power supplies as low as ±2.25V, and quiescent current is only 700μA—ideal for battery operated

systems. Internal input protection can withstand up to ±40V without damage. The INA128/INA129 is available in 8-pin plastic DIP, and SO-8 surface-mount packages, specified for the –40°C to +85°C temperature range. The INA128 is also available in dual configuration, the INA2128.
