Dual op-amp with rail-to-rail output for single-supply signal chains
The Maxim Integrated MAX4246AUA+ is a dual, general-purpose operational amplifier with rail-to-rail output, designed for single-supply operation from 2.5 V to 5.5 V. It delivers a gain-bandwidth product of 1 MHz and a slew rate of 0.4 V/µs, drawing just 375 µA per channel. The output swings within millivolts of both rails, which is critical for maximizing dynamic range in low-voltage ADC drivers, sensor buffers, or active filters where every bit of headroom counts. The -40°C to 125°C temperature range suits it for industrial control, automotive cabin electronics, and outdoor telecom modules.
Package and footprint
Housed in an 8-pin uMAX/uSOP (3.00 mm width) surface-mount package, the MAX4246AUA+ shares the same footprint as many standard MSOP-8 op-amps. The supplier device package is 8-uMAX/uSOP, and it ships in tubes. For reflow assembly, the 0.118" body width matches common land patterns; no special pad geometry required.
Lifecycle and compliance
The MAX4246AUA+ is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect. For new designs, this part is available through independent distribution and quoted to order against an RFQ.
