Product details

Single-supply rail-to-rail output op-amp in 8-µMAX

The 12 MHz gain-bandwidth product and 17 V/µs slew rate give it enough loop gain and slew margin to handle audio-band signals and moderate-speed data acquisition without excessive distortion.

The 12 MHz gain-bandwidth product sets the usable closed-loop bandwidth: at a gain of 10, expect roughly 1.2 MHz small-signal bandwidth before the open-loop gain rolls off. The 17 V/µs slew rate is enough to reproduce a 5 V peak-to-peak sine wave up to about 540 kHz without slew-induced distortion — adequate for audio line drivers, active filters, and ADC front-end buffering.

It is not specified for industrial or automotive temperature ranges, so avoid it for outdoor, under-hood, or factory-floor designs without a qualification review. The supply current is 2 mA typical, which keeps the thermal rise low in the 8-µMAX package.

Frequently asked questions

Can MAX473CUA operate from a single 3.3 V supply?

Yes. The rail-to-rail output can swing within millivolts of the 3.3 V rail and ground, preserving dynamic range in low-voltage systems.

Is MAX473CUA equivalent to AD8605?

No, they are not direct equivalents. The AD8605 is a CMOS-input op-amp with picoamp-level bias current and lower offset, while the MAX473CUA uses a bipolar input stage with 80 nA bias current and 700 µV offset. The pinouts differ (AD8605 is in SOT-23-5 or MSOP-8), so they are not drop-in replacements without board layout changes.

What is MAX473CUA's listed slew rate?

The listed slew rate is 17 V/µs. This is a typical value; for large-signal step response at the full 5.25 V supply swing, expect the output to slew at this rate, which sets the maximum undistorted frequency for a given output amplitude.
