Signal bandwidth and power budget for battery-powered sensor conditioning
The MAX4076EUK+T: The 230 kHz gain-bandwidth product sets the usable closed-loop bandwidth — at a gain of 10, the -3 dB point lands around 23 kHz, which covers most industrial sensor outputs (pressure transducers, thermocouples, current shunts) without rolling off the signal. Drawing 45 µA quiescent supply current, this op-amp fits into always-on sensor nodes or battery-powered data loggers where the amplifier's own draw must stay below 100 µA to meet annual battery life targets. Rail-to-rail output stage lets the amplifier swing within 10-20 mV of the supply rails — useful when running from a 2.5 V minimum supply span, where every millivolt of headroom matters for the ADC input range.
Package and reflow considerations for the SOT-23-5
Housed in a SOT-23-5 (SC-74A) package, the part uses a standard footprint with 0.95 mm pitch — the pick-and-place machine handles it without nozzle changes, and the reflow profile follows the standard lead-free ramp-soak-spike curve for small-outline packages.
Lifecycle and compliance status
RoHS3 compliant per the manufacturer's declaration — no exemptions that would require special handling for EU-market shipments.
