Each of the four amplifiers draws 45 µA of supply current, making it a fit for multi-channel sensor interfaces, battery monitors, and portable instrumentation where every microamp counts. The 1 MHz gain-bandwidth product and 0.92 V/µs slew rate are enough for audio-band filtering, ADC drive, and low-speed control loops, while the 2.7 V to 5.5 V supply span lets it run from a single lithium cell or a regulated 3.3 V / 5 V rail. The -40°C to 125°C operating range covers industrial and automotive cabin environments. ## 45 µA per channel — what that means for the power budget At 180 µA total quiescent for all four amplifiers, this op-amp leaves headroom for the rest of the signal chain in a battery-powered design. The 30 mA output current per channel can drive moderate loads like a reference input or a small headphone, but the part is not intended for high-current line drivers. The low bias current of 4 pA suits high-impedance sources such as pH probes or photodiode transimpedance stages, though the 1 mV input offset means the designer should budget for a calibration step if sub-millivolt accuracy is needed. ## Package and temperature grade for production planning Housed in a 14-SOIC package (3.90 mm body width), this part is a drop-in for standard quad op-amp footprints. The surface-mount package is compatible with reflow soldering; the ROHS3 compliance simplifies EU and global compliance. The industrial temperature range (-40°C to 125°C) means the part can be specified for outdoor telecom cabinets, engine-bay sensors, and factory-floor I/O modules without a temperature-grade upcharge.","metaTitle":"AD8544ARZ-REEL7 Quad Rail-to-Rail Op-Amp, 1 MHz","metaDescription":"ADI AD8544ARZ-REEL7 quad general-purpose op-amp, rail-to-rail output, 1 MHz GBW, 0.92 V/µs slew rate, 45 µA per channel, -40°C to 125°C, 14-SOIC.
