INA333AIDGKRG4

微功率（ 50毫安） ，泽尔？ -Drift ，轨到轨输出仪表放大器 Micro-Power 50mA, Zer?-Drift, Rail-to-Rail Out Instrumentation Amplifier

DESCRIPON

The INA333 is a low-power, precision instrumentation amplifier offering excellent accuracy. The versatile 3-op amp design, small size, and low power make it ideal for a wide range of portable applications. A single external resistor sets any gain from 1 to 1000. The INA333 is designed to use an industry-standard gain equation: G = 1 + 100kΩ/RG.
