Product details

10 µV offset, 50 µA supply — the precision trade-off

That offset spec is the headline — it means the part resolves microvolt-level signals from a bridge or thermocouple without the zero-error eating into the measurement budget. The 50 µA supply makes it viable for loop-powered 4-20 mA transmitters or battery-operated sensor nodes where every microamp is accounted for.

150 kHz bandwidth — what it buys and where it limits

The -3 dB bandwidth is 150 kHz with a 0.16 V/µs slew rate. That combination tells you this is a precision part, not a high-speed one. It handles DC and low-frequency AC signals cleanly — think strain-gauge conditioning, RTD front-ends, or medical instrumentation where the signal of interest is below a few kilohertz. If your application needs to digitize a 100 kHz ripple or fast transient, the INA333 will round the edges; the slew rate is the limiter.

Supply range and rail-to-rail output

That matters when you are running off a 3.3 V ADC reference and cannot afford a volt of headroom loss.

The 8-VSSOP package (3.00 mm width) is a compact surface-mount footprint suitable for dense PCB layouts. The G4 suffix indicates TI's green (RoHS) lead-finish — no compliance surprises for EU or California markets.

The base product number INA333 is shared across several package and tape options, so the AIDGKRG4 suffix locks in the 8-VSSOP reel variant.

Frequently asked questions

What is the difference between INA333AIDGKRG4 and INA333AIDGKR?

The difference is the packaging and reel format. The INA333AIDGKRG4 suffix indicates a green (RoHS) lead-finish and Tape & Reel packaging, while the INA333AIDGKR is the standard non-green variant. The electrical specifications — 10 µV offset, 50 µA supply, 150 kHz bandwidth — are identical between the two.
