Quad op-amp with rail-to-rail output and precision input stage
The MAX40078AUD+ is a quad general-purpose operational amplifier from Analog Devices, built for signal conditioning, filtering, and data-acquisition front-ends. It delivers a 10 MHz gain-bandwidth product and a 10V/µs slew rate, enough for audio-band and moderate-speed sensor signals. The rail-to-rail push-pull output stage swings within millivolts of both supply rails, which preserves dynamic range on a 2.7 V to 5.5 V single supply. Input bias current sits at 0.3 pA and input offset at 30 µV, so it handles high-impedance sources like photodiode amplifiers or pH probes without excessive DC error. The four channels share a 2.2 mA supply current, keeping the thermal budget manageable in a 14-TSSOP package. Operating temperature spans -40°C to +125°C, covering industrial and automotive under-hood environments.
Lifecycle and sourcing
Sourcing runs through independent distribution; availability and current pricing are confirmed when an RFQ is placed. For dual-source planning, check the family's quad op-amp portfolio — pin-compatible alternatives exist within the same supply and bandwidth class, but no official second-source MPN is listed.
