The -3 dB bandwidth of 150 kHz is the practical upper limit for the input signal before gain rolls off; for a thermocouple or strain-gauge bridge running at DC to a few hundred hertz, this is plenty of margin, but it rules out applications like high-speed data acquisition or audio above the audio band. The 10 µV input offset voltage means the amplifier resolves microvolt-level signals without external nulling, which is the spec that separates a true in-amp from a general-purpose op-amp pressed into differential service. ## 50 µA quiescent — the battery-life enabler Quiescent supply current is 50 µA, which puts this part in the micropower class. For a loop-powered 4-20 mA transmitter or a battery-operated data logger running off a CR2032 coin cell, that 50 µA is a small fraction of the total budget — the amplifier itself won't dominate the sleep current. Rail-to-rail output preserves the full ADC input range when the supply is tight. ## Package and thermal: 8-WFDFN exposed pad The INA333AIDRGR comes in an 8-WFDFN exposed pad package, supplier device package 8-SON (3x3 mm). The 125°C upper limit means it can sit next to a motor driver or inside an engine bay ECU without derating. The 70 pA input bias current stays low across temperature, which is important when the source impedance is high — a 10 kΩ bridge with 70 pA bias contributes only 0.7 µV of offset error.","metaTitle":"TI INA333AIDRGR Instrumentation Amp, 150 kHz, 10 µV Offset","metaDescription":"Texas Instruments INA333AIDRGR precision instrumentation amplifier: 150 kHz bandwidth, 10 µV offset, 50 µA supply.
