Texas Instruments INA333 Datasheet
The INA333 is a low‑power precision instrumentation amplifier featuring a typical offset voltage of 25 µV (max), input bias current of 200 pA (max), and a quiescent current of only 50 µA. It operates from a supply voltage range of 1.8 V to 5.5 V and provides a high common‑mode rejection ratio of at least 100 dB.
The device supports gain settings from 1 to 1000 via a single external resistor (G = 1 + 100 kΩ/RG) and is offered in 8‑pin VSSOP and 8‑pin WSON packages. It is suitable for bridge‑type amplifiers, ECG, pressure sensors, thermocouples, RTD amplifiers, portable instruments, and other industrial measurement applications. This manual is written in Chinese.
