Dual CMOS op-amp for signal conditioning in tight spaces
The MAX4233AUB+T is a dual CMOS operational amplifier from Analog Devices, packing two rail-to-rail output channels into a 10-MSOP footprint. Its 10 MHz gain-bandwidth product and 10V/µs slew rate suit it for fast signal chains — think sensor amplification or ADC driver stages where settling time matters. Each channel draws 1.2 mA supply current and can deliver 200 mA output drive, enough to swing into a 50-ohm load or drive a low-impedance ADC input. The 2.7 V to 5.5 V supply span means it runs from a single 3.3 V or 5 V rail without a separate negative supply.
Industrial temperature grade and low input bias
Rated for -40°C to 125°C operating temperature, this part fits into engine-bay or factory-floor electronics where ambient heat exceeds the commercial 85°C ceiling. The 1 pA input bias current keeps the DC error negligible in high-impedance sensor front-ends — a photodiode or pH probe sees no measurable loading. Input offset voltage is 850 µV typical, which is adequate for 8- to 10-bit signal chains but not for microvolt-level precision. The CMOS input stage gives the low bias, while the rail-to-rail output swings within 50 mV of each supply rail at light load.
Package and sourcing posture
Supplied in 10-TFSOP or 10-MSOP (0.118" wide), the MAX4233AUB+T mounts on the board surface — the 3.00 mm width fits into space-constrained layouts where a SOIC-8 would be too wide. The Tape & Reel option is the standard for pick-and-place assembly; Cut Tape is also available for prototype runs. Analog Devices lists the part as Active and ROHS3 compliant.
