Each of the four channels draws 31 µA supply current, keeping the total quiescent load under 125 µA. The 400 kHz gain-bandwidth product suits low-frequency signal paths — think pressure-sensor bridge amplifiers, thermocouple cold-junction compensation, and battery-current shunt monitors in engine-control or body-control modules. ## 400 kHz GBW — where it fits At 400 kHz GBW, this op-amp is deliberately a low-frequency part. It handles DC-accurate sensor conditioning, active filtering below 40 kHz, and slow control loops — not audio or high-speed ADC drivers. Compare it to the TSZ182IDT (3 MHz GBW, 4.7 V/µs slew rate) if you need wider bandwidth; the TSZ124IQ4T trades speed for lower quiescent current and a quad-channel count in a small 3x3 mm package. ## Sourcing and supply The TSZ124IQ4T is an active STMicroelectronics line, available through independent distribution. We source and quote it to order against an RFQ.","metaTitle":"STMicroelectronics TSZ124IQ4T Zero-Drift Op-Amp, 400 kHz","metaDescription":"ST TSZ124IQ4T quad zero-drift op-amp, 400 kHz GBW, 1 µV offset, 31 µA per channel.
