Precision front-end for low-power sensor chains
It delivers rail-to-rail output swing, a 10 µV input offset voltage, and 50 µA supply current — a combination that suits battery-powered bridge, thermocouple, and strain-gauge interfaces.
The 150 kHz -3 dB bandwidth and 0.16 V/µs slew rate set the INA333AIDGKTG4 for DC to low-frequency AC measurements — think thermocouple linearisation, load-cell readout, or ECG front-ends. The 70 pA input bias current keeps errors low when driving from high-impedance sources like pH probes or piezoelectric sensors.
Housed in an 8-VSSOP (MSOP-8) package, the INA333AIDGKTG4 occupies minimal board area — the 3 mm × 3 mm footprint fits dense mixed-signal layouts.
