The Analog Devices MAX4094AUD+T is a quad general-purpose op-amp in a 14-TSSOP package, with rail-to-rail output and a 500 kHz gain-bandwidth product. It operates from a single 2.7 V to 6 V supply, drawing 130 µA per channel. The 30 µV input offset voltage and 0.2 V/µs slew rate suit it for sensor conditioning, signal buffering, and low-frequency filter stages in industrial or automotive environments rated from -40°C to 125°C.
Rail-to-rail output and 500 kHz GBW — what they mean for the signal chain
The rail-to-rail output swing lets this op-amp drive an ADC input or a comparator threshold near the supply rails without headroom loss. The 500 kHz gain-bandwidth product sets the usable closed-loop bandwidth.
Supply current and offset — the power and precision trade-off
At 130 µA per channel, the MAX4094AUD+T sits in the low-power tier of general-purpose op-amps. The 30 µV input offset voltage is notably low for this current class.
Package and footprint — 14-TSSOP on the board
The 14-TSSOP (4.40 mm width) is a standard fine-pitch surface-mount package. It is compatible with common pick-and-place equipment and reflow profiles. The supplier device package is 14-TSSOP.
Lifecycle and sourcing
The MAX4094AUD+T is listed as Active with ROHS3 compliance. There is no end-of-life notice or last-time-buy window. For new designs or production replenishment, this part is sourced and quoted to order through independent distribution — availability and current pricing are confirmed at quote time against an RFQ.
