With a gain-bandwidth product of 400 kHz and a 0.2 V/µs slew rate, this is a low-speed precision amplifier, not a high-speed ADC driver. It is designed for sensor signal conditioning, bridge amplifiers, thermocouple interfaces, and other applications where DC accuracy and low drift dominate the selection criteria. ## 18 µA per channel — sizing the power budget Each of the two amplifiers draws 18 µA of supply current, for a total of 36 µA at no load. That places this part in the micropower class, suitable for battery-powered instruments, loop-powered 4-20 mA transmitters, and energy-harvesting sensor nodes. The supply range spans 1.8 V to 6 V, so it runs directly from a single lithium cell or a 3.3 V / 5 V regulated rail without an extra LDO. The rail-to-rail output swings within millivolts of either supply, preserving dynamic range at low supply voltages.","metaTitle":"ISL28233FBZ Zero-Drift Op-Amp, 2 µV Offset, 8-SOIC","metaDescription":"Renesas ISL28233FBZ dual zero-drift op-amp: 2 µV input offset, 400 kHz GBW, 18 µA supply per channel, -40°C to 125°C.
