INA129MDREP

精密低功耗仪表放大器 PRECISION, LOW POWER INSTRUMENTATION AMPLIFIERS

The INA129-EP device is a low power, general-purpose instrumentation amplifier offering excellent accuracy. The versatile 3-op amp design and small size make the device 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 INA129-EP provides an industry-standard gain equation; the INA129-EP gain equation is compatible with the AD620.

The INA129-EP device is laser trimmed for very low offset voltage, drift, and high common-mode rejection 113 dB at G ≥ 100. It operates with power supplies as low as ±2.25 V, and quiescent current is only 750 µA–ideal for battery operated systems. Internal input protection can withstand up to ±40 V without damage.

The INA129-EP is available in a 8-Pin SOIC surface-mount package specified for the –55°C to 125°C temperature range.
