INA333AIDGKR Description

Short technical summary and product information.

The Texas Instruments INA333AIDGKR is a low-power, precision instrumentation amplifier designed for excellent accuracy and versatility. Its 3-operational amplifier design, small size, and low power consumption make it ideal for a wide range of portable applications.

 

Key electrical specifications include a low offset voltage of 25 μV (G ≥ 100), excellent offset voltage drift of 0.1 μV/°C (G ≥ 100), and low noise density of 50 nV/√Hz (G ≥ 100). It boasts high common-mode rejection ratio (CMRR) of 100 dB (G ≥ 10) and low input bias current of 200 pA.

 

The device operates with supply voltages ranging from 1.8 V to 5.5 V and features a low quiescent current of 50 μA. The input voltage range is (V-) +0.1 V to (V+) -0.1 V, and the output range is (V-) +0.05 V to (V+) -0.05 V. It supports adjustable gain from 1 to 1000, set by a single external resistor using the equation G = 1 + (100 kΩ / RG).

 

The INA333AIDGKR is available in an 8-pin VSSOP (DGK) package, suitable for surface mount applications. It operates across a wide temperature range of -40°C to 125°C.
