Each amplifier draws 130 µA of supply current. The rail-to-rail output helps keep the signal swing high without needing a separate rail-to-rail input stage.
This part is safe to qualify for new production BOMs and ongoing builds.
Yes, the 2.7V to 6V supply range and rail-to-rail output make it well suited for single-supply designs. No negative rail is needed for signals near ground.
Within the same function class, the MAX4094AUD+ competes with other quad rail-to-rail op-amps in the 500 kHz GBW range, such as the MCP6004 from Microchip (1 MHz GBW, 1.8V to 6V) or the TSV914 from ST (8 MHz GBW, 2.5V to 5.5V). The MAX4094AUD+ offers a lower 30 µV offset than the MCP6004's typical 4.5 mV, making it the better choice for precision DC applications. Pin compatibility varies — verify the pinout against your PCB layout before substituting.
