Product details

What the 200 kHz bandwidth and 0.4 V/µs slew rate mean for your signal chain

The INA126U/2K5: The 200 kHz -3 dB bandwidth sets the usable frequency range for precision amplification — adequate for bridge-type sensors (strain gauges, load cells) and biomedical front ends (ECG, EEG) where the signal of interest lives below a few tens of kilohertz.

Low supply current and wide voltage range — battery or rail trade-off

Quiescent current is 175 µA typical.

Input offset and bias current — the precision floor

Input offset voltage is 100 µV typical with 10 nA input bias current.
