Dual op-amp with 10 MHz GBW and rail-to-rail output
The Maxim Integrated MAX4477AUA+T is a dual-channel, general-purpose operational amplifier that delivers 10 MHz gain-bandwidth product and a 3V/µs slew rate from a 2.7 V to 5.5 V supply range. Rail-to-rail output swing and push-pull drive let it interface directly with ADCs or drive moderate loads without external level shifting. Input bias current of 1 pA and offset voltage of 70 µV suit precision sensor conditioning — photodiode amplifiers, thermocouple buffers, or battery-monitoring front ends. The 8-uMAX/uSOP package (3 mm × 3 mm footprint) fits space-constrained boards in industrial control, portable instrumentation, and automotive-adjacent environments where the -40°C to 125°C temperature range is required.
Package and ordering code
Cut Tape (CT) quantities are also listed for prototype and low-volume builds. The physical package is an 8-lead uMAX/uSOP (MicroMAX, 3.00 mm body width), which is the same footprint as a standard MSOP-8. Surface-mount assembly is required — no through-hole variant exists for this part.
Lifecycle and sourcing
The MAX4477AUA+T carries an Active product status from Maxim Integrated (now part of Analog Devices). No end-of-life notice or last-time-buy schedule has been issued. ROHS3 compliance is confirmed. No second-source or pin-compatible alternate is documented in the available records, so dual-sourcing would require a separate qualification effort.
