INA128:130dB CMRR、700?A、低功耗、精密仪表放大器

  • INA129 - ?Identical performance with different gain equation.
  • INA131 - ?Improve input offset

The INA128 and INA129 are low-power, general purpose instrumentation amplifiers offering excellent accuracy. The versatile 3-op amp design and small size make these amplifiers ideal for a wide range of applications. Current-feedback input circuitry provides wide bandwidth even at high gain (200 kHz at G = 100).

A single external resistor sets any gain from 1 to 10,000. The INA128 provides an industry-standard gain equation; the INA129 gain equation is compatible with the AD620.

The INA12x is laser-trimmed for very low offset voltage (50 ?V), drift (0.5 ?V/°C) and high common-mode rejection (120 dB at G ≥ 100). The INA12x operates with power supplies as low as ±2.25 V, and quiescent current is only 700 ?A, ideal for battery-operated systems. Internal input protection can withstand up to ±40 V without damage.

The INA12x 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 a dual configuration, the INA2128.
